Summary
Two siblings presented with trigonocephaly, Wilson's disease, and facial dysmorphism, despite normal karyotypes and no identified ATP7B gene mutations. This case highlights a complex presentation of these distinct conditions.
Area of Science:
- Genetics
- Pediatrics
- Neurology
Background:
- Trigonocephaly is a craniosynostosis due to metopic suture fusion.
- Wilson's disease (hepatolenticular degeneration) results from copper accumulation due to impaired excretion.
- Typically, trigonocephaly lacks a single identified gene, while Wilson's disease is linked to the ATP7B gene.
Observation:
- Two siblings from a nonconsanguineous family presented with both trigonocephaly and Wilson's disease.
- Facial dysmorphism was noted in both siblings.
- Additional anomalies included renal agenesis in the female and undescended testis in the male.
Findings:
- Karyotypes for both siblings were normal.
- No mutations in the ATP7B gene were identified in the affected siblings or their parents.
- This suggests a potential genetic or etiological link beyond the known ATP7B gene for Wilson's disease in this family.
Implications:
- This case challenges the current understanding of the genetic basis for Wilson's disease and trigonocephaly.
- Further research is needed to explore potential novel genetic factors or complex inheritance patterns.
- Highlights the importance of comprehensive evaluation in syndromic presentations.
