Summary
Partial trisomy 15, a genetic condition, was identified in a newborn exhibiting head and extremity malformations. This chromosomal abnormality was linked to a translocation involving chromosomes 5 and 15, present in the mother and maternal grandfather.
Area of Science:
- Genetics
- Human Genetics
- Medical Genetics
Background:
- Partial trisomy refers to the presence of an extra part of a chromosome.
- Chromosomal abnormalities can lead to congenital malformations.
- Translocations are a type of chromosomal rearrangement.
Purpose of the Study:
- To report a case of partial trisomy 15 in a newborn.
- To investigate the genetic basis of observed malformations.
- To identify familial chromosomal abnormalities.
Main Methods:
- Karyotyping of the newborn and familial members.
- Clinical examination of the affected infant.
- Genetic analysis to identify chromosomal translocations.
Main Results:
- The newborn presented with partial trisomy 15.
- Congenital malformations of the head and extremities were observed.
- A balanced translocation, t(5;15), was identified in the mother and maternal grandfather.
Conclusions:
- Partial trisomy 15 can result in significant congenital anomalies.
- Familial translocations are a crucial consideration in cases of recurrent chromosomal abnormalities.
- Genetic counseling is recommended for families with known translocations.
