Ambry Genetics RCV001013850 SCV001174485 pathogenic Hereditary cancer-predisposing syndrome 2019-07-17 criteria provided, single submitter clinical testing The c.195delC pathogenic mutation, located in coding exon 3 of the PTEN gene, results from a deletion of one nucleotide at nucleotide position 195, causing a translational frameshift with a predicted alternate stop codon (p.Y65*). While this exact alteration has not been reported in the literature, different mutations resulting in the same stop codon (c.195C>A and c.195C>G) have been reported in individuals with suspected Cowden syndrome (Alfares et. al. Mol. Genet. Metab. 2017 06;121(2):91-95; Tan et. al. Am. J. Hum. Genet. 2011 Jan;88(1):42-56; D'Gama Neuron 2015 Dec;88(5):910-917). In addition to the information presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
