What is A patient with genotype 46 XY diagnosed of having androgen insensitivity syndrome. TRUE about androgen insensitivity syndrome is: and explain in detail?
These patients have a male karyotype with a mutation of the androgen receptor on the X chromosome. They have normal testicular development and endocrine function. However, because the internal and external male sexual structures need testosterone for development, they are absent. This results in a female phenotype. Secondary sexual characteristics (female) develop as a result of peripheral conversion of testosterone to estradiol, effectively resulting in unopposed estrogen stimulation.
