GeneDx RCV000627614 SCV000748614 pathogenic not provided 2018-04-12 criteria provided, single submitter clinical testing The c.2947delG variant in the SCN1A gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The c.2947delG variant causes a frameshift starting with codon Valine 983, changes this amino acid to a Serine residue, and creates a premature Stop codon at position 2 of the new reading frame, denoted p.Val983SerfsX2. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.2947delG variant is not observed in large population cohorts (Lek et al., 2016). We interpret c.2947delG as a pathogenic variant.
