Summary
Roberts-SC phocomelia syndrome (RS) is a rare genetic disorder causing limb defects and developmental issues. This report details a case with similar features, suggesting a potential variant of RS with unique organ abnormalities.
Area of Science:
- Genetics
- Developmental Biology
- Clinical Medicine
Background:
- Roberts-SC phocomelia syndrome (RS) is an autosomal recessive disorder characterized by severe limb malformations, craniofacial anomalies, and intellectual disability.
- Previous research linked RS to premature heterochromatin separation in chromosomes.
Observation:
- A case report of an infant presenting with clinical and radiological features consistent with Roberts-SC phocomelia syndrome.
- The infant exhibited symmetric limb defects, craniofacial abnormalities, and growth and mental retardation.
- Additionally, the patient presented with a rudimentary gallbladder and an accessory spleen.
Findings:
- Chromosomal analysis in the reported infant showed similarities to findings in known RS patients.
- The presence of a rudimentary gallbladder and accessory spleen are novel observations in this context.
Implications:
- This case expands the phenotypic spectrum of Roberts-SC phocomelia syndrome.
- It suggests a possible variant of RS, highlighting the importance of considering associated visceral anomalies.
- Further research is warranted to understand the genetic and developmental mechanisms underlying this potential RS variant.
