Trisomy 10p, due to an unusual translocation
Journal De Genetique Humaine
|January 1, 1985
Summary
A boy with developmental delays, short stature, and congenital anomalies was found to have trisomy 10p. This genetic condition resulted from a specific translocation between chromosomes 10 and 14.
Area of Science:
- Genetics
- Clinical Medicine
- Developmental Biology
Background:
- Congenital anomalies and developmental delays can stem from various genetic factors.
- Chromosome abnormalities are a significant cause of birth defects and intellectual disability.
Observation:
- A case study describes a male child presenting with intellectual disability, short stature, craniofacial dysmorphia, clubfeet, and hypertonia.
- The patient exhibited multiple congenital anomalies, suggesting a complex underlying genetic cause.
Findings:
- Karyotype analysis identified trisomy 10p, indicating an extra copy of the short arm of chromosome 10.
- The trisomy 10p was specifically linked to a balanced translocation between chromosomes 10 and 14, denoted as t(10;14)(p11;p12).
Implications:
- This case highlights the phenotypic variability associated with trisomy 10p.
- Understanding such translocations is crucial for genetic counseling and diagnosing similar cases.
- Further research into the specific genes on 10p involved in development is warranted.
