This CNV falls in the AUTS1 region of linkage to ASD (7q21-q32, OMIM#209850).14, 15, 16, 17, 18 A fine mapping study of AUTS1 previously reported association of ASD with SNPs in two genes that are proximal to ZNF277, DOCK4 (dedicator of cytokinesis 4, OMIM#607679) and IMMP2L (IMP2 inner mitochondrial membrane protease-like, OMIM#605977).19 An additional investigation20 described a rare microdeletion involving the DOCK4 and IMMP2L genes that co-segregated with the presence of dyslexia in an extended family. The gene discussed is DOCK4; the disease is dyslexia.
