A defect in regulator genes could affect the development of the sexual anatomy, resulting in a discrepancy between genetic and physical sex. This disorder is called androgen insensitivity syndrome (AIS), which affects the expression or function of genes that influence the body's response to androgens (male sex hormones). As a consequence, the fetus with XY chromosomes (i.e., male) may fail to develop male-typical genitalia and instead develop female-typical genitalia or ambiguous genitalia. This disorder is not caused by a faulty dominant-recessive pattern, Down syndrome, or a sex-linked disorder because it involves a different pathway of gene expression and hormone action.
