GeneDx RCV000599228 SCV000710266 likely pathogenic not provided 2017-12-13 criteria provided, single submitter clinical testing The c.1867dupT variant in the DNMT3A gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The c.1867dupT variant causes a frameshift starting with codon Tyrosine 623, changes this amino acid to a Leucine residue, and creates a premature Stop codon at position 7 of the new reading frame, denoted p.Tyr623LeufsX7. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.1867dupT variant is not observed in large population cohorts (Lek et al., 2016). We interpret c.1867dupT as a likely pathogenic variant.
