Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003231001 SCV003929373 likely pathogenic Intellectual disability, X-linked, syndromic 33 2023-04-05 criteria provided, single submitter clinical testing Variant summary: TAF1 c.3467-1G>A is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: Four predict the variant abolishes the canonical 3' acceptor site and three predict that the variant also strengthens/creates a new 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 180585 control chromosomes (gnomAD). To our knowledge, no occurrence of c.3467-1G>A in individuals affected with Mental Retardation, X-Linked, Syndromic 33 and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
