Partial trisomy 16q resulting from maternal translocation 11p/16q
Annales De Genetique
|January 1, 1984
Summary
This study details a male child with partial trisomy 16q, a condition arising from a maternal chromosome 11p;16q translocation. Clinical observations are compared with existing literature on this rare genetic disorder.
Area of Science:
- Human Genetics
- Clinical Cytogenetics
- Pediatric Medicine
Background:
- Maternal balanced translocation (11p;16q) is a rare chromosomal abnormality.
- Partial trisomy of chromosome 16 long arm (16q) can result from such translocations.
- Understanding the phenotypic consequences of specific trisomies is crucial in genetic counseling.
Observation:
- A 3.5-year-old male presented with clinical features associated with partial trisomy 16q.
- The patient's condition was a direct result of a maternal balanced translocation involving chromosomes 11 and 16.
- Detailed clinical observations were recorded for this specific case.
Findings:
- The case illustrates a specific instance of partial trisomy 16q.
- Comparison with existing literature helps delineate the spectrum of clinical findings in trisomy 16q.
- The maternal translocation provides a clear genetic mechanism for the observed trisomy.
Implications:
- This case contributes to the understanding of genotype-phenotype correlations in chromosomal abnormalities.
- Further research can refine diagnostic criteria and genetic counseling for families with similar translocations.
- Highlights the importance of cytogenetic analysis in diagnosing developmental disorders.
