GeneDx RCV000189055 SCV000242686 pathogenic not provided 2014-08-26 criteria provided, single submitter clinical testing c.140delA: p.Asn47MetfsX45 (N47MfsX45) in exon 1 of the SCN1A gene (NM_001165963.1). The normal sequence with the base that is deleted in braces is GAAA{A}TGGC.The c.140delA mutation in the SCN1A gene causes a frameshift starting with codon Asparagine 47, changes this amino acid to a Methionine residue and creates a premature Stop codon at position 45 of the new reading frame, denoted p.Asn47MetfsX45. This mutation is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Although this mutation has not been previously reported to our knowledge, its presence is consistent with a diagnosis of SCN1A-related disorder. The variant is found in INFANT-EPI panel(s).
