SRY and neurodevelopmental disorder: As we know, whole exome gene sequencing provides a diagnosis in 25–29% of individuals with disorders suggestive of a genetic etiology in pediatric and adult populations[19] and it is a first-tier clinical diagnostic test for individuals with neurodevelopmental disorders.[20] Therefore, in order to confirm the SRY gene in the diagnosis of testicular DSD, the accuracy of whole exome gene sequencing is markedly better than PCR.
