AR and complete androgen insensitivity syndrome: Molecular genetic etiology can be determined in the majority of CAIS cases, whereas other factors may be involved in AIS as AR mutation is not always identified in CAIS cases, and phenotype–genotype correlation in cases with AR mutations is still unclear as the identical AR mutation (p.P914S) can be detected in both CAIS and PAIS with different phenotypes (4, 26, 65).
