THREE SIBLINGS WITH ANDROGEN INSENSITIVITY SYNDROME

Genetic, gonadal, phenotypic and psychological genderis the basis for gender assignment to an individual. Derangement in genetic makeup, under or over exposure to sex hormones and problems related to sex hormone receptors will lead to abnormal development of the external and internal genitalia. Failure to respond for the endogenous androgen, Androgen Insensitivity Syndrome is one of the common causes of genital ambiguity and intersex. In this case series we have presented three girls from a family of seven children visited Tikur Anbassa Specialized Hospital (TASH) with a complaint of primary amenorrhea and diagnosed to have androgen insensitivity syndrome. Their clinical presentation, relevant laboratory and histopathologic findings, karyotype and genetic analysis results are summarized. Potential causes and treatment options are discussed.
