Behavioural, developmental and psychological characteristics in children with germline PTEN mutations: a carer report study.
Kids with PTEN mutations show autism-like sensory and anxiety issues plus self-injury, yet social motivation may stay intact—screen and support accordingly.
01Research in Context
What this study did
Cummings et al. (2024) asked 20 parents to fill out online forms. The parents all have a child with a PTEN gene mutation.
The forms asked about daily living skills, autism traits, mood, and self-injury. No tests or therapy were given.
What they found
Most kids scored below average on everyday self-care. Many showed strong sensory issues, worry, and body-hitting.
Yet the same kids often tried to chat or play with others. Social interest stayed even when skills lagged.
How this fits with other research
de Leeuw et al. (2024) and Smith et al. (2022) saw the same pattern in 16p11.2 kids: high sensory and behavior problems. All three studies used parent surveys, so the match is strong.
Green Snyder et al. (2016) looked at 16p11.2 duplication and found only one-fifth had clear autism. That seems to clash with K’s high autism traits, but LeeAnne used strict clinic rules while K counted any feature. The gap is about labels, not facts.
McGhee et al. (2025) link a different gene, PTPN11, to autism traits. Together the papers tell us: check for autism signs any time a rare gene change is known.
Why it matters
If you serve a child with a PTEN mutation, expect low adaptive scores and big sensory needs. Do not assume poor social drive—pair social teaching with sensory breaks. Screen for anxiety and self-injury early and add replacement skills before problem behavior grows.

03Original abstract
BACKGROUND: PTEN is primarily known as a tumour suppressor gene. However, research describes higher rates of difficulties including intellectual disability and difficulties relating to autism spectrum conditions (ASCs) in people with germline PTEN mutations. Other psychological characteristics/experiences are less often reported and are explored in this study. METHODS: The parents of 20 children with PTEN mutations completed an online survey exploring adaptive behaviour, ASC-associated behaviours, anxiety, mood, hypermobility, behaviours that challenge, sensory experiences, quality of life and parental wellbeing. Published normative data and data from groups of individuals with other genetic neurodevelopmental conditions were used to contextualise findings. RESULTS: Overall levels of adaptive behaviour were below the 'typical' range, and no marked relative differences were noted between domains. Higher levels of ASC-related difficulties, including sensory experiences, were found in comparison with 'typically developing' children, with a possible peak in restrictive/repetitive behaviour; ASC and sensory processing atypicality also strongly correlated with reported joint hypermobility. A relative preservation of social motivation was noted. Anxiety levels were found to be elevated overall (and to relate to sensory processing and joint hypermobility), with the exception of social anxiety, which was comparable with normative data. Self-injurious behaviour was common. CONCLUSIONS: Results suggest a wide range of possible difficulties in children with PTEN mutations, including elevated anxiety. Despite elevated ASC phenomenology, social motivation may remain relatively strong. Firm conclusions are restricted by a small sample size and potential recruitment bias, and future research is required to further explore the relationships between such characteristics.
