Ambry Genetics RCV001019081 SCV001180393 pathogenic Hereditary cancer-predisposing syndrome 2021-04-14 criteria provided, single submitter clinical testing The c.319+3A>C intronic pathogenic mutation results from an A to C substitution 3 nucleotides after coding exon 1 in the CHEK2 gene. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing that results in the loss of coding exon 1 in the set of samples tested (Ambry internal data). Sequence variations that modify the initiation codon are expected to result in either loss of translation initiation, N-terminal truncation, or cause a shift in the mRNA reading frame. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
