Cognitive and behavioral functioning in Coffin-Siris syndrome and epilepsy: a case presentation

Area of Science:

• Neuroscience
• Genetics
• Developmental Psychology

Background:

• Coffin-Siris syndrome (CS) is a rare genetic disorder with limited understanding of its early neurobehavioral presentation.
• Clinical features include digital hypoplasia, characteristic facial features, and frequently, callosal agenesis on MRI.
• Epilepsy is a common comorbidity, further complicating the neurodevelopmental profile.

Observation:

• A comprehensive neuropsychological evaluation was conducted on a 7.5-year-old child with CS and epilepsy.
• Parental ratings assessed adaptive functioning and behavioral patterns.
• Specific assessments included the Mullen Scales of Early Learning and the Behavior Assessment for Children (BASC-2).

Findings:

• The child exhibited limited attentional abilities.
• Receptive language skills (AE: 3-3) were stronger than expressive language skills (AE: 1-4).
• Adaptive functioning was significantly impaired across all domains (Vineland Adaptive Behavior Composite AE: 1-9).
• Behavioral observations included social deficits, stereotyped behaviors, restricted interests, and ritualistic play, without significant mood disturbances.

Implications:

• The study highlights a diffuse pattern of neurobehavioral deficits in children with Coffin-Siris syndrome and epilepsy.
• Multidimensional assessment techniques, including adaptive behavior evaluation, are crucial for capturing the full spectrum of developmental sequelae.
• Further research is warranted to better understand and manage the complex needs of individuals with CS.
