Automated Fluorescence Analysis of CAG Repeats at the Human Androgen Receptor Gene (HUMARA)

Abstract
The HUMARA CAG repeats polymorphism was studied in an Italian population sample. Polymerase chain reaction amplification and automated fluorescent analysis were used. A total of 19 and 15 repeats was observed in female and male subjects, respectively, and one new allele was found. The authors conclude that this X-linked short tandem repeat, typed without ambiguity and with a heterozygosity of 0.902, is useful in parentage testing of female subjects.
