Standing Tall For XYY Syndrome

Creating positive steps for XYY Syndrome.

XYY Syndrome Awareness


Today I attended an event “Light Up Lakelands – Local Heroes” as I had been nominated in recognition for my efforts in creating awareness for XYY Syndrome.

It was a wonderful morning, meeting the other nominees, making connections within the local community and raising the profile of XYY Syndrome.

Thank you to everyone for nominating me as a finalist, creating awareness is very important for the future of families, like ours, experiencing life with XYY Syndrome.

Adam’s Story

Hi, I’m Adam

I have 47 XYY syndrome with is a genetics disorder. It affects 1 in 1000 male births. Problems it may cause is learning disabilities, low muscle tone, delayed motor skills including coordination, balance etc. Many boys suffer from emotional or behavioural issues.

What i would like to do is help this charity to make a small profit from my fundraiser and hopefully make people more aware of the syndrome and how it affects different individuals.

If you would like any more information about the syndrome then please feel free to ask me or alternatively if you would like to read about it unique have an area about 47 XYY syndrome.

Please donate any money at all to this charity they help to provide information to families and people that suffer from all sorts of different genetics disorders.

You want just be helping me, you will be helping anyone that has a genetics disorder. Please share this post to help raise awareness.

Awareness Event For XYY Syndrome

Awareness Event For XYY Syndrome

Come show your support for families, children, teenagers , adults diagnosed with XYY Syndrome.

Only males are born with XYY Syndrome and only a true diagnosis can be made by genetic testing( blood test)

Our son was born with XYY Syndrome and needs daily support, however his diagnosis is not recognised as needing specialised support and we have funded a lot on our own.

My husband and I decided to host this awareness event to share our story and share as much information as we can for all XYY boys, teenagers, adults & families that need support and like us have found it very hard to find the support that’s needed.

On our journey we have come across many other XYY families, boys, teenagers and adults online just like us, the common thread is that this diagnosis is just pushed aside.

I hear this a lot, we get told just give him love and you’ll be ok. We do, but we need so much more support and understanding then that.

Please help us and show your support by sharing the awareness for XYY Syndrome.

Creating awareness for males born with XYY Syndrome and this is our story.

Creating awareness for males born with XYY Syndrome

 This is our story

From the age of two we started to notice our son wasn’t developing along the same lines as is generally expected for a child his age.

After many attempts to work out what was causing the delays in reaching developmental milestones, he was finally diagnosed by having a genetic blood test -XYY Syndrome was his diagnosis at the age of 4.

Due to difficulties experienced with speech and comprehension, he became increasingly frustrated at not being able to communicate his needs and wants effectively.

This therefore created problems with his ability to control his emotions and delayed his social development.

We found that encouraging him to participate in social groups, sports and community events, he gradually developed some of the skills required to effectively engage with the world around him.

Now, at the age of six he loves to socialise even if he does still require some additional support and guidance.

At the end of the day though, he is still a young boy who loves nothing more than playing and having fun!

Our son’s characteristics

Below we have listed a few characteristics our son has displayed over the years:

  • more than above average height
  • difficulty controlling emotions
  • screams a lot
  • loses self within emotions
  • emotionally immature
  • finds it hard to self soothe and regulate behaviour
  • difficulty comprehending certain questions or situations
  • task avoidance
  • muscle weakness
  • requires additional support and guidance in social situations
  • requires additional help at school
  • holds a conversation with himself
  • enjoys making animal noises
  • impulse control

 Support Networks

Over the last three years we have been working hard to find the appropriate support networks available but it has not been easy. This is when we decided to start creating awareness ourselves for XYY Syndrome and sharing our experiences.

Out of the kindness of our hearts we would like to share our story and our resources so that we may help other boys, men and families like ours.

We love our son and this is only the start of our journey.




XYY Syndrome Australia

This is very important,

Unfortunately, and incredibly, there is no funding provided for the boys, men and families living with XYY Syndrome on a daily basis.

That is why we are sharing our story in the hope we may increase awareness and one day soon receive the recognition this disorder deserves.

Please help spread the awareness.

Warmest regards

Dave and Amber






Summary of XYY Syndrome studies

A Summary of Recent Research Papers on 47, XYY (XYY)

XYY Syndrome confirmed by a blood test is a rare genetic disorder. Both the chromosome aneuploidy disorders, 47,XYY (XYY) and 47,XXY (Klinefelter syndrome, KS) only affects males, and although both disorders are relatively common, they are under-diagnosed, (Ross et al, 2010). Some of the physical aspects of XYY syndrome include tall stature and flat feet as well as neurological, cognitive, and behavioural phenotypes (Ross et al, 2010). Bardsley, et al., (2013) points out that although 1:1000 boys have the karyotype 47, XYY (XYY), there is a lack of information about this disorder, and approximately 85% or more of males with XYY are never diagnosed. Recent studies typically describe boys diagnosed for clinical reasons in the first decade of life because of developmental delays, behavioural issues and tall stature. Language delays have been recognised in various studies of XYY (Bardsley, et al 2013, Ross, et al 2012, Ross, et al 2015), Tartaglia et al 2015).

Ross et al (2012), found that the XYY boys studied had verbal learning disabilities, attention deficits, delayed speech development requiring speech therapy, an increased risk of impulsivity and difficulties related to behavioural dysregulation. In both this research and Bardsley, et al (2013), research found nearly all the XYY boys studied needed speech and/or reading therapy, most of them also needed occupational and /or physical therapy with half of them receiving special education services at school. Bardsley, et al (2013), in their research found even higher percentages of XYY boys needed these services. Ross et al (2012), research also found that boys with XYY have an increased risk for features consistent with Autism Spectrum Disorders (ASD). These include features that overlap considerably with ASD, such as language disorders, other social deficits, and anxiety/withdrawal symptoms.

Various research on XYY shows that boys with this disorder can have varying degrees of learning difficulties. Previous research shows that Verbal IQ is limited by delayed speech development and it is a common factor with XYY boys, that they need speech therapy and extra help in the school environment, (Ross et al, 2010).

In a study contrasting the behavioural and social phenotypes included a screen for autistic behaviours in boys with 47,XYY and KS it was found that a subset of the XYY and KS groups had behavioural difficulties that were more severe in the XYY group. The researchers recommended that boys diagnosed with XYY or KS should receive a comprehensive psycho-educational evaluation. They should also be screened for learning disabilities, attention-deficit/hyperactivity disorder, and ASD (Ross et al 2012).

In a comparison study that included a control group, a research group found boys with XYY Syndrome as with KS have varying levels of language impairment at both simple and complex levels. Both the XYY and the KS boys performed less well, on average than the control group in tests of general cognitive ability, language, achievement, verbal memory, and in some aspects of attention and motor function. They found that there is some overlap in the cognitive phenotypes in these two disorders, especially in language dysfunction. The researchers found that the boys with XYY had more severe and pervasive language impairment and that the XYY boys and were less likely than the KS or the control group to complete the full evaluation because of a tendency for less cooperation for the evaluation. General cognitive profiles of both XYY boys and the KS boys showed decreased verbal and non-verbal abilities (Ross et al 2010).

Note: Non-completion of tasks seems to be a common theme with XYY boys and indicates that shorter assessments with breaks or alternative assessments would work better.

In language and achievement delayed speech, impaired word retrieval, speed of linguistic processing, expressive and receptive capabilities and processing of narration has been described in previous research in both XYY and KS groups. However, in Ross et al, (2010) research they pointed out that the XYY group appears to have a more severe and pervasive language impairment that the KS group. The researchers also found varying levels of complexity in oral and written language. The researchers noted a greater impairment in the XYY group, particularly for higher-level metalinguistics abilities. This was demonstrated by a significant difficulty in understanding figurative language, interpreting ambiguities in language, as well as in oral expression and verbal memory, (Ross et al, 2010).

This language impairment appears to have important academic implications. Boys with XYY produced lower achievement in reading and spelling, compared to both KS and the control group. The researchers’ findings are similar to previous studies in XYY and report school difficulties out of proportion to what would be expected based on IQ.

Often these boys have difficulty following school curricula and need educational support services in reading and writing. This research points out that XYY boys are at increased risk for having delayed motor milestones and impaired fine and gross motor function, coordination and tone. (Ross et al 2010).

Ross et al (2010) points out that the research on XYY and KS have important neuro-cognitive and educational implications. From the educational side, the difficulty in complex language processing and impaired attention as well as motor function identified in XYY and KS populations may be missed. This can be a challenge to educators. Further, Ross et al 2010 pointed out that it is critical for boys with both these disorders to receive appropriate education interventions that target their specific learning challenges, (Ross et al 2010), (Ross et al 2012).

The eXtraordinarY Kids Clinic was established in Colorado USA to provide comprehensive and experience care for children and adolescents with sex chromosome aneuploidies (SCAs) of which 47, XYY is included. The researchers, Tartaglia et al (2015) found that the rates of SCA diagnoses in infants and children are increasing in America and this clinic provides specialised interdisciplinary care to address associated risks. SCA children are born with an atypical number of X and/or Y chromosomes, and present a range of medical, developmental, educational, behavioural and psychological concerns. Tartaglia et al (2012) points out that SCAs are the most common chromosomal abnormalities in humans and are estimated to occur in 1:400 individuals. The addition of extra X and/or Y chromosomes leads to neuro-developmental differences, with increased risk for developmental delays, language-based learning, cognitive impairments, executive dysfunction, and behavioural and psychological disorders. Searle (2016) points out that sometimes children with the same genotype will show similar problems. However, even children with the same genotype can differ in some or even nearly all of their problems.

Importantly Tartaglia et al (2012) points out that there is there is significant variability in the presence and severity of associated neuro-developmental and psychological problems among individuals with SCA. However, the researchers commonly encountered patterns of weaknesses in language, verbal cognition, reading and executive function (EF). In the trisomy conditions (XXY, XYY and XXX) the majority of studies reported cognitive scores within the low average to average range. However, cognitive scores are often lower that expected for family history, and up to 85% of SCAs require special education supports for learning disabilities. In all SCA conditions, there are additional increased risks for emotional disorders including anxiety, depression, and other mood disorders, as well as medical problems such as seizure, which can make the neuropsychological and behavioural phenotypes even more complex.

Tartaglia et al (2015) found a lack of expertise with SCA among medical providers, psychologists, developmental paediatricians, and other specialist/therapists involved in the care of children with SCAs. As a result, parents/caregivers often do not have access to experienced providers who can incorporate all different aspects of SCA in to understanding how the child’s disorder affects their health, behaviour, learning, and overall daily functioning. This requires caregivers to ‘piece together’ evaluations, as well as to educate the professionals working with children about SCA. Tartaglia et al (2015) reported that there was a better understanding of SCAs but more is needed to educate healthcare providers, psychologists, therapists, and educators nationally about SCA conditions so that families receive better information after receiving a diagnosis.

Note: Parents and caregivers with XYY boys have found this a typical experience. (XYY Facebook feedback, 2016).

In another study by Tartaglia, et al (2012) looking at 4 types of SCA (XXY, XYY XXX and XXYY) they described attention problems, hyperactivity and impulsivity as behavioural features associated with SCA and found that children and adolescents with SCA are at an increased risk for ADHD symptoms.

Note: I found that most of the research on XYY comes out of the USA as the references below show. I only looked at current research to find a better solution to understanding XYY Syndrome. The eXtraordinarY Kids Clinic in the USA multi-disciplinary specialist approach are developing a better understanding of how the child’s SCA disorder affects their health, behaviour, learning, and overall daily functioning. Unfortunately, there is no such clinic in Australia.

Some definitions follow – but for further clarification search further on the internet.

Syndrome – Sometimes a particular chromosome disorder will give a similar pattern of problems. If enough children are born with the similar pattern, it is called a Syndrome.
Chromosome – Searle, B, (2016), explains that apart from the mother’s egg cells or the father’s sperm cells, every cell in the human body normally contains 23 pairs of chromosomes, with 46 chromosomes in total in each cell. The first 22 pairs of chromosomes are called the Autosomes and are numbered from 1 to 22 according to their length, starting with no 1 as the longest. The 23rd pair of chromosomes are called the Sex Chromosomes. Sex chromosomes are labelled X or Y. Males normally have one copy of the X chromosome and one copy of the Y chromosome in each cell, while females normally have two copies of the X chromosome and none of the Y chromosome.
Rare Chromosome Disorders (RCD) – Searle, B, (2016) explains RCDs include extra, missing or re-arranged chromosome material but do not include the more common chromosome conditions such as Down’s Syndrome. The amount of chromosome material duplicated, missing or re-arranged can vary a great deal. This means that it may be difficult to identify two people who have exactly the same chromosome disorder. The clinical problems of those affected can also vary enormously even when the chromosome diagnoses are similar.
Aneuploidy – is the presence of an abnormal number of chromosomes in a cell eg. 45 or 47 chromosomes.
Genotype – is a description of a person’s chromosome make-up.
Phenotypes – is the observable physical characteristics of a person’s genotype.
Karyotype – gives the bigger picture seen under a light microscope
Behaviour Dysregulation – behavioural impairment in the regulation of a metabolic, physiological, or psychological process
Cognitive Impairments – describes certain limitations in skills such as communication, self-help, and social skills. These limitations will cause a child to learn and develop at a slower rate.
Executive Dysfunction – is a disruption to the efficiency of the executive function, which is a group of cognitive processes that regulate, control and manage other processes.
Neurodevelopmental Disorders – impairment and development of the brain that affects emotion, learning ability, self-control and memory and unfolds as the individual grows.

What is XYY Syndrome


Wikipedia XYY Syndrome

Unique– Understanding Chromosome Disorders

XYY Syndrome is a genetic condition that occurs when a male’s genes have an extra Y chromosome. Females typically have two X chromosomes (XX). Males typically have one X chromosome and one Y chromosome (XY). Males with this genetic condition have an extra copy of the Y chromosome in each of their cells (XYY).

Most people have 46 chromosomes in each cell. Males with XYY syndrome have 47 because of the extra copy of the Y chromosome. However, sometimes this mutation is only present in some cells. According to the National Institutes of Health, XYY syndrome occurs in 1 out of every 1,000 boys (Genetics Home Reference).

XYY Syndrome is also sometimes called Jacob’s Syndrome, XYY Karyotype, or YY Syndrome.

Males with XYY Syndrome live typical lives for the most part. Some males with XYY Syndrome may be taller than average and face learning difficulties or speech problems. They may also grow up with minor physical differences, such as weaker muscles and bones and delayed puberty. When they are older, men with the syndrome may face fertility issues and complications related to low testosterone levels. Besides these complications, however, males with XYY syndrome do not usually have any distinguishing physical features or complications, and have normal sexual development.
