Ambry Genetics RCV001019366 SCV001180714 likely pathogenic Hereditary cancer-predisposing syndrome 2019-10-15 criteria provided, single submitter clinical testing The c.945+5G>A intronic variant results from a G to A substitution 5 nucleotides after coding exon 6 in the PTCH1 gene. This nucleotide position is highly conserved in available vertebrate species. A similar alteration at this location, c.945+5G>T (designated as 933+5G>T) has been reported in an individual with features consistent with Nevoid Basal Cell Carcinoma Syndrome, also known as Gorlin syndrome (Fujii K et al. Hum. Mutat., 2003 Apr;21:451-2). Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to abolish the native splice donor site; however, direct evidence is unavailable. 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 classified as likely pathogenic.
