The androgen receptor is a member of the family of nuclear receptors. In its activated form as an androgen receptor ligand complex (the ligand can either be testosterone or 5a-dihydrotestosterone), the androgen receptor is able to regulate a specific expression of target genes. The androgen receptor is expressed at high levels in male reproductive tissues. Mutations in the androgen receptor gen...

Androgens drive male secondary sexual differentiation and maturation. Mutations in the androgen receptor (AR) gene cause an array of abnormal sex differentiation phenotypes in humans, ranging from mild through partial to complete androgen insensitivity. Earlier, we reported a C3693T missense mutation in the AR gene in a familial case of complete androgen insensitivity syndrome (CAIS), resulting...

OBJECTIVE To study the clinical profile and the management of patients with disorders of sex development (DSD). DESIGN AND SETTING Retrospective study from a tertiary care hospital of North India. METHODS AND PATIENTS One hundred ninety-four patients of DSD registered in the Endocrine clinic of Postgraduate Institute of Medical Education and Research, Chandigarh between 1995 and 2014 were in...

We present data to suggest the existence of a mental retardation (MR) locus at Xq11.2-q12 between DXS1 and DXS905, identified in two subjects with complete androgen insensitivity syndrome (CAIS) and MR. Androgen insensitivity syndrome is a disorder of male sexual differentiation caused by a defect in the androgen receptor (AR) gene (Xq11-q12). Two subjects with CAIS resulting from a complete de...

Normal human development requires the compatibility between genetic sex (sex chromosomes), sex of gonades (tests or ovaries), genitalia (external and internal sex organs), somatic features (body characteristics) and psychic sex. The psychic sex, called frequently gender, consist of gender identity (self-estimation), gender role (objective estimation) and sexual orientation (hetero- or homosexua...
