5-Alpha-Reductase Deficiency
Excerpt
Ambiguous genitalia is a very rare problem encountered in newborns, with a prevalence of 1 in 4500 live births. Even with the recent advances in technology like genetic workup, an assay of hormones, and karyotyping, only 20% to 40% of the time can the diagnosis be made in these children. 5-alpha-reductase type 2 (5α-RD2) deficiency is one of the important causes of ambiguous genitalia in children. The phenotype of children with 5α-RD2 deficiency can vary from underdeveloped male genitalia to a complete female phenotype.
