Majority of CAH patients were compound heterozygous for the mutations. 63.6% of CAH patients were females while males constituted 36.3% of total CAH patients in the present cohort. There was high frequency of i2g mutation in CYP21A2 gene among CAH patients. Genotypes were grouped in four groups on basis of underlying combination of mutations. Genotyping plays a pivotal role in genetic counseling of patients and their families.
