GeneDx RCV000489676 SCV000576985 pathogenic not provided 2018-01-24 criteria provided, single submitter clinical testing The c.5389_5392dupATCT pathogenic variant in the TSC2 gene causes a frameshift starting with codon Serine 1798, changes this amino acid to a Tyrosine residue and is expected to extend the open reading frame to an unknown length, denoted p.Ser1798TyrfsX?. Three other frameshift variants downstream of c.5389_5392dupATCT have been reported in the Human Gene Mutation Database in association with tuberous sclerosis complex (Stenson et al., 2014), supporting the functional importance of this region of the protein. Furthermore, the c.5389_5392dupATCT variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Although this pathogenic variant has not been previously reported to our knowledge, its presence is consistent with the diagnosis of tuberous sclerosis complex in this individual.
