4 MUTATIONS OF THE ANDROGEN RECEPTOR GENE IN THE ANDROGEN INSENSITIVITY SYNDROME. (AIS)

Complete Androgen Insensitivity Syndrome in Three Sisters

Mutational analysis of the androgen receptor gene in two Chinese families with complete androgen insensitivity syndrome

Androgens are essential for normal male sex differentiation and are responsible for the normal development of male secondary sexual characteristics at puberty. The physiological effects of androgens are mediated by the androgen receptor (AR). Mutations in the AR gene are the most common cause of androgen insensitivity syndrome. The present study undertook a genetic analysis of the AR gene in tw...

A novel mutation of the androgen receptor gene in familial complete androgen insensitivity syndrome.

OBJECTIVE Androgen insensitivity syndrome (AIS) is characterized by androgen receptor (AR) dysfunction. Its main characteristic is a female phenotype in an individual with a 46, XY karyotype. The molecular basis of this disorder was investigated in two individuals with familial AIS. PATIENTS AND METHODS The diagnoses of the two individuals were confirmed using ultrasonography, hormonal analys...

A missense mutation in the androgen receptor gene causing androgen insensitivity syndrome in a Chinese family

abnormalities. Therefore, the proband was confirmed to have AIS by clinical presentations, biochemistry, ultrasonography, and pathology. Genomic DNA was extracted from peripheral blood leukocytes using standard methods. All eight exons of AR were amplified by polymerase chain reaction (PCR) using appropriate primers designed by Primer Premier and Oligo (Premier Biosoft Co. Ltd., Palo Alto, Cali...

Androgen resistance caused by mutations in the androgen receptor gene.

Defects in the human androgen receptor cause a spectrum of defects in male phenotypic sexual development associated with abnormalities in the receptor protein assayed in cultured fibroblasts and in broken cell assays. In some patients these abnormalities are associated with absent ligand binding, in other qualitative or quantitative abnormalities of ligand binding are present, and in some no ab...
