SRY and Turner syndrome: Many investigators suggested co-amplification of SRY gene along with amelogenin for unambiguous gender identification.[11, 13–15] Turner syndrome (46,X0), Klinefelter syndrome (46,XXY), androgen insensitivity syndrome, and 47,XYY syndrome may show a discrepancy between the genotype and the phenotype of a person.[16] Dauwerse et al.[17] reported a case of an infertile male with normal development of male genitalia having 46,XX karyotype, but SRY gene was identified to be inserted onto the terminal end of chromosome 16.
