Mutation in the androgen receptor gene (AR) is known to cause androgen insensitivity syndrome (AIS). In an X-linked recessive manner, an AR mutation gets transmitted to the offspring through carrier mothers in 70% of cases, the other 30% arising de novo. However, reports on AR mutations amongst Indian patients with AIS are scarce in the literature. This study reports mutations in AR from two Indian families, each having a proband with partial androgen insensitivity syndrome (PAIS) phenotype. Clinical, endocrine and cytogenetic evaluation of these affected children was performed. Mutational analysis was carried out by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) analysis followed by sequencing. The two point mutations were in exon 5: p.M742I, familial in patient 1 and p.V746M de novo in patient 2. These are hitherto unrecognized mutations in our population. Similar mutational studies are suggested in patients with AIS, in order to identify their frequency and clinical severity in our population.
