GeneDx RCV000298867 SCV000329787 pathogenic not provided 2016-07-13 criteria provided, single submitter clinical testing The c.4223delG variant in the TSC2 gene has been reported previously in association with tuberous sclerosis complex (TSC) (TSC2 LOVD). It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The c.4223delG pathogenic variant in the TSC2 gene causes a frameshift starting with codon Glycine 1408, changes this amino acid to a Alanine residue and creates a premature Stop codon at position 3 of the new reading frame, denoted p.G1408AfsX3. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Therefore, we interpret the c.4223delG as a pathogenic variant.
