Ambry Genetics RCV000564974 SCV000667365 pathogenic Hereditary cancer-predisposing syndrome 2017-01-19 criteria provided, single submitter clinical testing The c.2336dupT pathogenic mutation, located in coding exon 15 of the APC gene, results from a duplication of T at nucleotide position 2336, causing a translational frameshift with a predicted alternate stop codon (p.L779Ffs*9). This mutation has been reported in multiple patients and families affected familial adenomatous polyposis (FAP) (Vandrovcová J et al. Hum. Mutat. 2004 Apr;23:397; Sheng JQ et al. World J. Gastroenterol. 2010 Mar;16:1522-6; Lagarde A et al. J. Med. Genet. 2010 Oct;47:721-2). Of note, this alteration is also designated as c.2336dup in published literature. In addition to the clinical data 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.
Myriad Genetics, Inc. RCV003337313 SCV004045569 pathogenic Familial adenomatous polyposis 1 2023-05-04 criteria provided, single submitter clinical testing This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation.
