Article Title: Understanding and Modifying the Behavior of Boys with XXYY: A Guide for Parents and Professionals
Author: Karen Riley, PhD
Date of Publication: 2007
This paper was originally commissioned by the XXYY Project. At the urging of Dr. Riley, the XXYY Project has generously shared their valuable “Behavior Paper” with AXYS.
While this paper focuses on the behavioral profile of XXYY, it will prove very valuable for any child who is experiencing behavior issues. This paper provides step-by-step instructions for coping with behavioral issues that many children with X and Y chromosome variations may experience to one degree or another.
We urge you to review this document and generally substitute your child’s condition for XXYY. In most cases, the fit is very good.
Once again, we offer our sincere thanks to the XXYY Project for sharing this important work with the AXYS community.

“Individuals with XXY may be at increased risk for depression. Routine screening for depressive symptoms and appropriate referral and evaluation may be warranted.”
Article Title: Role of the X Chromosome in Social Behavioural Dysfunction and Autism-like Behaviour

“Social cognitive competence appears to be a good predictor of social behaviour and adaptation. Individual variance in social cognitive competence is, for a substantial part, attributable to genetic factors. Deficits in social behaviour are seen in populations such as those with autism-spectrum disorders, and although social (dys)functioning may be similar at the level of behavioural phenotypes, it may substantially differ with regard to the underlying cognitive and genetic pathways. In this review study it is argued that there is a need to study the neurocognitive and behavioural phenotypes in more homogeneous genetic groups. This enables us to identify aetiological pathways to psychopathology. In both Turner syndrome (45, XO) and Klinefelter syndrome (47, XXY), basic social-cue processing deficits are observed, which may contribute to difficulties in social intuition and hence in coping with social situations. The study of these two syndromes opens up opportunities to study the influence of the X chromosome on brain behaviour developmental trajectories of social functioning and psychopathology in heterogeneous populations.”

Article Title: Structural and functional neuroimaging in Klinefelter (47,XXY) syndrome: a review of the literature and preliminary results from a functional magnetic resonance imaging study of language
Authors: K. Steinman, J. Ross, S. Lai, A. Reiss, F. Hoeft

Highly technical article that looks at various research studies associated with neurobiology and neuroimaging of 47,XXY brains. Could be a useful article for discussions with medical professionals interested in the underlying neuroanatomy involved with XXY. Also could be helpful for situations involving the legal system where it is important for the court to understand the neurobiological differences that can be present in XXY.

“Klinefelter syndrome (KS) or 47,XXY occurs in 1 in 650 males. Individuals with KS often present with physical characteristics including tall stature, hypogonadism, and fertility problems. In addition to medical findings, the presence of the extra X chromosome can lead to characteristic cognitive and language deficits of varying severity. While a small, but significant downward shift in mean overall IQ has been reported, the general cognitive abilities of patients with KS are not typically the intellectual disability range. Most studies support that males with KS have an increased risk of language disorders and reading disabilities.Results of other studies investigating the relationship between verbal and nonverbal/spatial cognitive abilities have been mixed, with differing results based on the age and ascertainment method of the cohort studied. Executive function deficits have been identified in children and adults with KS, however, the research in this area is limited and further investigation of the neuropsychological profile is needed. In this article, we review the strengths and weaknesses of previous cognitive and neuropsychological studies in males with KS in childhood and adulthood, provide historical perspective of these studies, and review what is known about how hormonal and genetic factors influence cognitive features in 47,XXY/KS.”

“This is the first quantitative study to show Klinefelter syndrome has a significant personal impact. Men diagnosed with Klinefelter syndrome later in life reported similar difficulties as those at younger ages, suggesting that they would benefit from early detection and intervention. Understanding factors influencing this can assist in providing adequate services to individuals with Klinefelter syndrome, their partners, families, and the health professionals caring for them.”
