Abstract
The SRD5A2 gene that encodes SRD5A2 enzyme is placed on chromosome 2p23. The coding region of the gene includes 5 exons that are translated into a 254-amino acid protein. To evaluate SRD5A2 gene that encodes SRD5A2 enzyme is placed on chromosome 2p23 accompany with biotidinase deficiency in case with ambiguous external genitalia. We investigated a case with ambiguous external genitalia for cytogenetic and gene mutation analaysis. Gene mutation analaysis and cytogenetic analaysis were performed according to a standard DNA sequencing method based on PCR and the present international standard nomenclature (ISCN), respectively. A Novel p.Arg179Ser (c.537 G>T) heterozygotes mutation on exon 3 of SRD5A2 gene accompany with biotidinase deficiency was detected. The chromosomal analaysis result is 46, XY. This is the first case with biotinidase deficiency and novel R179S p.Arg179Ser (c.537 G>T) mutation of the SRD5A2 gene, which cause 5-alpha reductase deficiency.
