Summary
A rare ring chromosome 6 was identified in a young girl with developmental delays and distinct physical features. This chromosomal abnormality may impact growth and cognitive development.
Area of Science:
- Genetics
- Human Chromosome Studies
- Pediatric Development
Background:
- Ring chromosomes are rare structural abnormalities.
- Chromosome 6 abnormalities can lead to various developmental issues.
Observation:
- A 5-year-old girl presented with psychomotor and growth retardation, microcephaly, and microphthalmia.
- Analysis revealed a ring-6 chromosome in the patient.
Findings:
- The breakpoints of the ring chromosome 6 are located distally on both arms.
- Human Leukocyte Antigen (HLA) phenotypes were normally transmitted, suggesting breakpoints are outside the HLA region.
Implications:
- This case expands the known examples of ring-6 chromosome.
- Understanding breakpoints is crucial for correlating genotype with phenotype.
- Further research is needed to fully elucidate the impact of ring-6 chromosome on development.
