Summary
This study details two brothers with Cockayne syndrome, highlighting cachectic dwarfism, developmental delays, and unique brain anomalies. A previously undescribed cerebellar arachnoid cyst was found in one patient during necropsy.
Area of Science:
- Genetics and rare diseases
- Pediatric neurology
- Clinical case studies
Context:
- Cockayne syndrome (CS) is a rare, autosomal recessive disorder characterized by premature aging, developmental and neurological abnormalities.
- Clinical manifestations of classical CS include cachectic dwarfism, microcephaly, intellectual disability, and photosensitivity.
- Genetic defects in DNA repair pathways underlie Cockayne syndrome.
Purpose:
- To present the clinical history and pathological findings of two brothers diagnosed with classical Cockayne syndrome.
- To document a potentially novel encephalic anomaly associated with Cockayne syndrome.
Summary:
- Two brothers presented with classical Cockayne syndrome, exhibiting severe growth retardation, intellectual disability, microcephaly, intracranial calcifications, and skin photosensitivity.
- One sibling, who died at age 10 from bronchopneumonia, underwent necropsy revealing significant encephalic anomalies.
- Notably, an arachnoidal cyst at the cerebellar base was identified, a finding not previously reported in Cockayne syndrome literature.
Impact:
- This case report expands the phenotypic spectrum of Cockayne syndrome.
- Highlights the importance of detailed pathological examination in rare genetic disorders.
- May inform future research into the neurological complications and genetic underpinnings of Cockayne syndrome.
