Partial D 15 trisomy. A case and general review
Human Heredity
|January 1, 1975
Summary
This study identifies a rare genetic condition in a girl with developmental delays and heart disease. The extra chromosome was identified as a partially deleted chromosome 15, contributing to her unique clinical presentation.
Area of Science:
- Genetics
- Clinical Medicine
- Cytogenetics
Background:
- Congenital heart disease and developmental delays can stem from various genetic anomalies.
- Accurate chromosomal identification is crucial for understanding rare genetic disorders.
Observation:
- A girl presented with profound intellectual disability, cyanotic congenital heart disease, myoclonic seizures, and strabismus.
- Karyotype revealed an extra small G-size chromosome with unique features, including projections on the long arms.
Findings:
- Giemsa-trypsin banding identified the extra chromosome as a partially deleted chromosome 15.
- This case aligns with 'partial trisomy 15' but presents distinct morphological characteristics.
Implications:
- This case expands the understanding of partial trisomy 15 phenotypes.
- The findings highlight the importance of detailed cytogenetic analysis in diagnosing complex genetic syndromes.
