Androgen receptor genotyping in a large Australasian cohort with androgen insensitivity syndrome; identification of four novel mutations.

Complete Androgen Insensitivity Syndrome in Three Sisters

A novel NR5A1 variant in an infant with elevated testosterone from an Australasian cohort of 46,XY patients with disorders of sex development

BACKGROUND NR5A1 loss-of-function mutations are increasingly found to be the cause of 46,XY disorders of sex development (DSD). OBJECTIVE To determine the presence of NR5A1 mutations in an Australasian cohort of 17 46,XY DSD patients with presumed androgen insensitivity syndrome (AIS) who were negative for androgen receptor gene (AR) mutation. DESIGN Exons 2-7 of NR5A1 were PCR amplified an...

Novel mutation in the ligand-binding domain of the androgen receptor gene (l790p) associated with complete androgen insensitivity syndrome.

Mutations in the X-linked androgen receptor (AR) gene cause androgen insensitivity syndrome (AIS), resulting in an impaired embryonic sex differentiation in 46,XY genetic men. Complete androgen insensitivity (CAIS) produces a female external phenotype, whereas cases with partial androgen insensitivity (PAIS) have various ambiguities of the genitalia. Mild androgen insensitivity (MAIS) is charac...

Functional analysis of novel androgen receptor mutations in a unique cohort of Indonesian patients with a disorder of sex development.

Mutations in the androgen receptor (AR) gene, rendering the AR protein partially or completely inactive, cause androgen insensitivity syndrome, which is a form of a 46,XY disorder of sex development (DSD). We present 3 novel AR variants found in a cohort of Indonesian DSD patients: p.I603N, p.P671S, and p.Q738R. The aim of this study was to determine the possible pathogenic nature of these newl...

Androgen Receptor Mutations Associated with Androgen Insensitivity Syndrome: A High Content Analysis Approach Leading to Personalized Medicine

Androgen insensitivity syndrome (AIS) is a rare disease associated with inactivating mutations of AR that disrupt male sexual differentiation, and cause a spectrum of phenotypic abnormalities having as a common denominator loss of reproductive viability. No established treatment exists for these conditions, however there are sporadic reports of patients (or recapitulated mutations in cell lines...
