The Valine Allele of the V89L Polymorphism in the 5-α-Reductase Gene Confers a Reduced Risk for Hypospadias

Abstract: This finding is in accordance with the assumption that functional polymorphisms may play an important role in complex disorders such as hypospadias when several genes as well as environmental factors contribute to the etiology.

“…The role of amplification of the CAG repeats remains to be determined [113] and may be associated with undermasculinized genitalia, including hypospadias [114]. For some authors, the V89L variant of the SRD5A2 gene is a risk factor for hypospadias [115], whereas for others it is not [116]. Polymorphisms of the estrogen receptor may also facilitate the deleterious effects of xenoestrogens since their effects are mainly mediated through this receptor.…”

“…1,2 It can be defined as a defect in the normal development of the urethra, foreskin and ventral aspect of the penis, and may be classified as simple (glandular or penile) and severe (scrotal or perineal) on the basis of the anatomical location of the urethral meatus. The cause of hypospadias is complex, and still elusive to date, especially in mild cases.…”

“…Hypospadias is probably a complex disorder caused by both genetic and environmental influences, either alone or in a combination. 2,3 Because the formation of the male urethra is fully androgen-dependent, it seems that a more reasonable theory to explain hypospadias is an abnormality in the pathway of the androgen metabolism. Indeed, those defects in some molecules involved in the pathway, like SRY, SOX9, AR, SRD5A2 and WT1, might contribute to the abnormal male development including a subset of hypospadias.…”
