Ambry Genetics | RCV000492484 | SCV000581072 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2016-12-14 | criteria provided, single submitter | clinical testing | The p.C488R variant (also known as c.1462T>C), located in coding exon 10 of the PTCH1 gene, results from a T to C substitution at nucleotide position 1462. The cysteine at codon 488 is replaced by arginine, an amino acid with highly dissimilar properties. This alteration was detected as a de novo finding in an individual with clinical history consistent with Nevoid basal cell-carcinoma syndrome (Ambry internal data; Bree AF et al. Am. J. Med. Genet. A, 2011 Sep;155A:2091-7). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. |
