[Physiopathology of androgen insensitivity syndromes. Contribution of molecular biology].

Molecular genetic study of androgen insensitivity syndrome is now easier by the development of powerful molecular tools. Complementary DNA of the androgen receptor gene has been recently cloned and sequenced. The development of cDNA probes gave the opportunity to study DNA restriction fragment length polymorphisms of patients with complete or partial androgen insensitivity syndrome.
