Androgen insensitivity sy (Androgen insensitivity sy (Testicular Testicular feminization syfeminization sy))
The most common form, The most common form, complete androgen complete androgen insensitivity syndrome (testicular insensitivity syndrome (testicular feminization)feminization), results from mutations in the , results from mutations in the gene for the androgen receptor.This gene is gene for the androgen receptor.This gene is located at Xq11-Xq12, and hence this located at Xq11-Xq12, and hence this disorder is inherited as an X-linked disorder is inherited as an X-linked recessive. recessive.
