RCV000431832 | SCV000517203 | pathogenic | not provided | 2018-01-02 | criteria provided, single submitter | clinical testing | The R176X variant in the PEX16 gene has been reported previously in association with autosomalrecessive Zellweger syndrome when present in the homozygous state or when in trans with anotherpathogenic variant (Honsho et al., 1998; Ohba et al., 2013). One study has shown that the R176Xvariant inactivated PEX16, which impaired peroxisome and peroxisomal membrane vesicle formation(Honsho et al., 1998). This variant is predicted to cause loss of normal protein function either throughprotein truncation or nonsense-mediated mRNA decay. The R176X variant was not observed inapproximately 6500 individuals of European and African American ancestry in the NHLBI ExomeSequencing Project, indicating it is not a common variant in these populations. We interpret R176X as a pathogenic variant. |

RCV001851705 | SCV002243717 | pathogenic | Peroxisome biogenesis disorder | 2023-12-28 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg176*) in the PEX16 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PEX16 are known to be pathogenic (PMID: 9837814, 11890679, 20647552, 20681997). This variant is present in population databases (rs61752117, gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of Zellweger spectrum disorder (PMID: 9837814, 24091540). ClinVar contains an entry for this variant (Variation ID: 6466). For these reasons, this variant has been classified as Pathogenic. |
