Additionally, we identified 13 novel candidate genes (ARSF, BAHD1, CHST7, CUL2, FRMPD3, KCNC4, LFNG, RGS4, RNF133, SCRN2, SLC12A8, USP24, and ZNF746) with limited information or whose specific mechanisms linking their variants to the autism phenotype are not yet understood (Table S1). The gene discussed is CUL2; the disease is autism.
