Phenotypic diversity in siblings with partial androgen insensitivity syndrome.

Genotype versus phenotype in families with androgen insensitivity syndrome.

Androgen insensitivity syndrome encompasses a wide range of phenotypes, which are caused by numerous different mutations in the AR gene. Detailed information on the genotype/phenotype relationship in androgen insensitivity syndrome is important for sex assignment, treatment of androgen insensitivity syndrome patients, genetic counseling of their families, and insight into the functional domains...

Phenotypic variation and detection of carrier status in the partial androgen insensitivity syndrome.

The partial androgen insensitivity syndrome occurs in 46,XY subjects with phenotypes ranging from perineoscrotal hypospadias with cryptorchidism and micropenis (mild undervirilisation) to clitoromegaly and partial labial fusion (marked undervirilisation). Within an affected family, wide variation in the degree of genital ambiguity between individuals can be seen. Two cousins of a previously rep...

Complete Androgen Insensitivity Syndrome in Three Sisters

Mutations of the androgen receptor gene identified in perineal hypospadias.

Hypospadias is a common urological abnormality and may occur in simple (glandular or penile) or severe forms (perineal). Perineal hypospadias often occurs in association with other genital abnormalities, such as bilateral cryptorchidism and micropenis, and may be the result of partial androgen insensitivity. We have investigated the androgen binding status and androgen receptor gene of boys fro...

Three Siblings with Androgen Insensitivity Syndrome.

Genetic, gonadal, phenotypic and psychological genderis the basis for gender assignment to an individual. Derangement in genetic makeup, under or over exposure to sex hormones and problems related to sex hormone receptors will lead to abnormal development of the external and internal genitalia. Failure to respond for the endogenous androgen, Androgen Insensitivity Syndrome is one of the common ...
