Ambry Genetics RCV000491358 SCV000579610 pathogenic Hereditary cancer-predisposing syndrome 2018-11-19 criteria provided, single submitter clinical testing The c.1600-2A>G intronic variant results from an A to G substitution two nucleotides upstream from coding exon 15 in the TSC2 gene. This nucleotide position is highly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted shift the native acceptor site upstream by one nucleotide, however, direct evidence is unavailable. This alteration has been observed as a de novo alteration in at least one individual who has a personal history that is consistent with TSC2-associated disease (Ambry internal data). In addition, alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
