Ambry Genetics RCV002453341 SCV002611981 pathogenic Hereditary cancer-predisposing syndrome 2020-05-29 criteria provided, single submitter clinical testing The c.3298delG pathogenic mutation, located in coding exon 28 of the TSC2 gene, results from a deletion of one nucleotide at nucleotide position 3298, causing a translational frameshift with a predicted alternate stop codon (p.V1100Cfs*3). This mutation was identified in tissue from a subependymal giant cell astrocytoma; however, it was not known if the individual had a clinical diagnosis of tuberous sclerosis (Martin KR et al. Nat Commun, 2017 06;8:15816). 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.
