Functional Characterization of Naturally Occurring Mutant Androgen Receptors from Subjects with Complete Androgen Insensitivity

Complete Androgen Insensitivity Syndrome in Three Sisters

Complete Androgen Insensitivity Syndrome.

The incidence of Complete Androgen Insensitivity Syndrome (CAIS) is about 1 in 20,000. People with CAIS are normal appearing females, despite the presence of testes and a 46, XY chromosome constitution. We came across a case in which a 17 years old girl presented with the complaint of inguinal hernia and amenorrhea. Subsequent investigations were done revealing absence of female internal genita...

Functional characterization of mutant androgen receptors from androgen-independent prostate cancer.

Mutations in the androgen receptor (AR), that alter steroid hormone specificity have been identified in a series of androgen-independent prostate cancers. To address the functional properties of these mutant ARs that may have contributed to their selection in vivo, responses to a series of steroid hormones and antiandrogens were assessed. CV-1 cells were cotransfected with wild-type or mutant A...

Complete androgen insensitivity syndrome caused by a novel mutation in the ligand-binding domain of the androgen receptor: functional characterization.

Mutations in the X-linked androgen receptor (AR) gene cause the androgen insensitivity syndrome by impairing androgen-dependent male sexual differentiation to varying degrees. Complete androgen insensitivity (CAIS) yields an external female phenotype, whereas affected cases of partial androgen insensitivity have various ambiguities of the genitalia. Here we describe a 46,XY phenotypically femal...
