Two cases were affected with androgen insensitivity syndrome (AIS) (missense mutation on exon 7, position c.3637 G>A: p.R841H and position c.3610 G>A: p.R832Q), one case was affected with 5-alpha-reductase deficiency type 2 (missense mutation at c.578A>G: p.N193S on exon 4), and 22 cases (88%) did not demonstrate AIS or 5α-RD2 gene abnormality.
