GeneDx RCV000312270 SCV000329784 pathogenic not provided 2018-10-03 criteria provided, single submitter clinical testing The c.826_827delAT pathogenic variant in the TSC2 gene has been reported multiple times previously in association with tuberous sclerosis complex (Niida et al., 1999; TSC2 LOVD). The deletion causes a frameshift starting with codon Methionine 276, changes this amino acid to a Valine residue and creates a premature Stop codon at position 61 of the new reading frame, denoted p.Met276ValfsX61. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Additionally, it was not observed in approximately 6,200 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Therefore, we consider c.826_827delAT to be a pathogenic variant.
