GeneDx RCV000479724 SCV000568799 pathogenic not provided 2018-06-07 criteria provided, single submitter clinical testing The R1637X nonsense variant in the CHD2 gene has been reported previously in as a de novo change in an individual with early onset absence epilepsy and photosensitive epilepsy (Galizia et al., 2015). The R1637X variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Therefore, R1637X is interpreted to be a pathogenic variant and its presence is consistent with the diagnosis in this patient
