CAH (Congenital adrenal hyperplasia) may be defined as a type of autosomal recessive disorder that can be expressed only in homozygous recessive condition only.
The CAH is mainly occur due to the deficiency of the enzyme 21-hydroxylase that affects the adrenal gland. This enzyme is important for the hormones like glucocorticoid, mineralocorticoid and androgens. The increase in the androgen level causes the development of more masculine activities in the female.
