Autistic features in Cohen syndrome: a preliminary report

Area of Science:

• Genetics
• Developmental Psychology
• Medical Research

Background:

• Cohen syndrome is a rare genetic disorder affecting connective tissues, primarily linked to chromosome 8q22.
• While physical characteristics are documented, psychological and behavioral development, particularly autism spectrum disorder (ASD) comorbidity, remains understudied.
• Previous observations suggested a potential dual diagnosis of autism in a subset of individuals with Cohen syndrome.

Purpose of the Study:

• To investigate the prevalence of autism spectrum disorder (ASD) symptoms in individuals with Cohen syndrome.
• To explore the psychological and behavioral development in a cohort of patients diagnosed with Cohen syndrome.
• To identify early indicators of ASD-related challenges in young children with Cohen syndrome.

Main Methods:

• A postal survey was conducted among parents of individuals with Cohen syndrome in the UK.
• Data were collected from 33 participants (18 males, 15 females; ages 2–45 years).
• Parental reports on social, communication, and behavioral patterns were assessed against DSM-IV/ICD-10 criteria for autism.

Main Results:

• Over half of the participants (19 out of 33) displayed impairments in social communication and exhibited rigid, stereotyped behaviors, meeting criteria for ASD.
• 'Autistic-type' behavioral patterns were observed with similar frequency in both males and females.
• Parental reports indicated that developmental difficulties were typically noted before the age of one year.

Conclusions:

• The high incidence of ASD symptoms in Cohen syndrome warrants further investigation.
• A significant overlap exists between Cohen syndrome and autism spectrum disorder, suggesting a need for integrated diagnostic approaches.
• Larger-scale studies are recommended to confirm these findings and explore the underlying genetic and physical characteristics.
