Examples of genes with such variants in multiple disorders were: PCMTD2 in ASD, OCD and SCZ; KNDC1 in ASD and SCZ; CARHSP1, PCMTD2, SYNM, and EXOC3 in both ASD and OCD; and GNG13, MRPS33, RPS3A, FAM69C, and CD24 in ASD and ADHD. This evidence concerns the gene GNG13 and attention deficit-hyperactivity disorder.
