Background: The common phenotype caused by NR5A1 mutations of 46,XY is gonadal dysgenesis without adrenal deficiency. Preserved fertility of the affected males was described in two patients with different mutations. No functional analysis of these two mutations has been done. Here we report brothers with isolated hypospadias who carries a novel heterozygous mutation of c.910G>A, E304K in NR5A1 gene. Their asymptomatic father carries the same nucleotide ch...

Background: Hypospadias is a relatively common form of 46,XY disorders of sex development. Although several genes have been implicated in the development of hypospadias, molecular basis of the majority of cases remain unknown. Recently, targeted disruption of lysine-specific demethylase 3A (KDM3A) were shown to cause defective sex development in male mice.Objective and hypotheses: The aim of this study was to clarify whether KDM3A mutations underlie hypo...
