Morris syndromeThe Morris syndrome. Androgen insensitivity syndrome (AIS) is a genetic disease caused by mutations in the androgen receptor gene. AIS patients are individuals with a 46, XY karyotype. The phenotype consists in female external genitalia, short vagina, absent mullerian structures, and abdominal, inguinal or intralabial primordial testes. Precise diagnosis, that differentiating between complete (CAIS) and partial (PAIS) form, requires clinical and hormonal investigation and is of great importance for appropriate gender assignment. The CAIS has a minimal impact of one in 99,000 births, for the PAIS, however, there aren’t some statistics available, but generally it should be with a lower impact, approximately ten times less than CAIS.
