FRMPD3 and autism: 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).
