GeneDx RCV000657614 SCV000779356 likely pathogenic not provided 2018-05-16 criteria provided, single submitter clinical testing The R795X variant in the PEX1 gene has been reported previously, along with a second variant in PEX1, in an individual with Zellweger syndrome (Collins and Gould, 1999). R795X has also been reported in the heterozygous state in an additional unrelated individual with a Zellweger spectrum disorder, however, there was no mention of a second variant being identified (Ebberink et al., 2011). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R795X variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). We interpret R795X as a likely pathogenic variant.
