Clinical summary

Help

Imported from OMIM

Hypospadias is a common congenital malformation of the penis, affecting approximately 1 in 750 births in Europe. Due to developmental arrest of urethral fusion, the urethral opening is displaced along the ventral side of the penis. The opening can be located glanular, penile, or even more posterior in the scrotum or perineum. Although most children with this condition undergo surgery in their second year of life, serious medical, social, and sexual problems may still exist later in life (summary by van der Zanden et al., 2011). Hypospadias is a feature of several syndromic disorders, including the androgen insensitivity syndrome (300068) and Opitz syndrome (300000). Genetic Heterogeneity of Hypospadias See also HYSP2 (300758), caused by mutation in the MAMLD1 gene (300120) on chromosome Xq28; HYSP3 (146450), a familial form which has been mapped to chromosome 7q32.2-q36.1; and HYSP4 (300856), a susceptibility locus mapped to chromosome Xp11.22 and associated with variation in the DGKK gene (300837).

Help

This panel should be performed in all individuals suspected of having an overlapping clinical phenotype. Confirmation of a clinical diagnosis through genetic testing can allow for genetic counseling and may direct medical management. Genetic counseling can provide a patient and/or family with the natural history of the condition, identify at-risk family members, provide reproductive risks as well as preconception/prenatal options, and allow for appropriate referral for patient support and/or resources.
