The AR protein (pictured) mediates the effects of androgens in the human body. Androgen insensitivity syndrome (AIS) is a condition involving the inability to respond to androgens, typically due to androgen receptor dysfunction. [1] It affects 1 in 20,000 to 64,000 XY (karyotypically male) births.
Jan 27, 2021 · Abstract. Complete androgen insensitivity syndrome (CAIS) is due to complete resistance to the action of androgens, determining a female phenotype in persons with a 46,XY karyotype and functioning testes. CAIS is caused by inactivating mutations in the androgen receptor gene (AR).

Jul 1, 2003 · Androgen insensitivity syndrome (AIS) is caused by mutations in the androgen receptor gene and is associated with a variety of phenotypes in 46,XY individuals, ranging from phenotypic women [complete form (CAIS)] to men with minor degrees of undervirilization or infertility [partial form (PAIS)].

Androgen insensitivity syndrome (AIS) occurs when someone is genetically male but is insensitive to androgens (male sex hormones). This means the person has male sex chromosomes (one X and one Y chromosome) but may have female genitals. AIS is a disorder of sex differentiation. It was previously called testicular feminization syndrome. It affects m...
There are three types of AIS: 1. Complete androgen insensitivity syndrome (CAIS):A person’s external genital appears female. But they don’t have female sex organs (no ovaries, fallopian tubes or uterus). People with CAIS are often raised as girls. 2. Partial androgen insensitivity syndrome (PAIS):A person’s external genitals may appear partially (n...
Males who inherit an abnormal gene, called the androgen receptor (AR) gene, from their mothers have a 1 in 4 chance of developing AIS. Females can also inherit and carry the gene, but they won’t develop AIS.
Androgen insensitivity syndrome is rare. About 1 in 99,000 male infants are born with partial androgen insensitivity syndrome and 2 to 5 per 100,000 are born with complete androgen insensitivity syndrome.
Oct 20, 2012 · The uterus, cervix, and proximal vagina are absent in complete androgen insensitivity syndrome because of the action of antimüllerian hormone produced by Sertoli cells of the testis. 4 The vagina varies from a dimple in the perineum to normal length, but is always blind-ending.
