Partial Trisomy 13 Plus Partial Trisomy 4q Due to Unusual Segregation of Translocation Chromosomes
Overview

The cytogenetic analysis of a 7-month-old retarded girl with clinical signs compatible with partial trisomy 13 revealed a translocation t(4;13)(q33;q14) and an additional derivative chromosome 13. This karyotype probably resulted from 3:1 segregation during meiosis of the patient's mother.
