Read our new study on CASK!

We partnered with the University of Cambridge to advance understanding of CASK-related disorders through new research findings.

Researchers examined neurodevelopmental challenges in individuals with CASK gene mutations by analysing two data sources: published reports covering 151 people with CASK gene variations, and fresh assessments of 31 children and young people participating in the BINGO study, a UK research initiative examining brain function and behaviour in rare genetic conditions.

Findings: neurodevelopmental difficulties in the BINGO cohort aligned with earlier research, though severe learning challenges, structural brain differences, and visual impairments appeared less frequently. Notably, cerebral visual impairment and sleep disturbances emerged as common issues in the BINGO group despite limited previous reporting. The presence of epilepsy — though not brain structure variations — correlated with reduced adaptive functioning.

Understanding the complete spectrum of CASK-related neurodevelopmental differences can guide families, healthcare providers and researchers in identifying monitoring and treatment priorities. The research highlights previously underrecognised areas including cerebral visual impairment and sleep complications requiring attention.

Limitations: the BINGO sample contained limited participants without a comparison control group; assessments of brain structure and epilepsy were restricted. Additional investigation is necessary regarding relationships between brain structure, epilepsy and behavioural outcomes.
