Description

NM_000466.2(PEX1):c.2770dupG(D924Gfs*5) is expected to be pathogenic in the context of peroxisome biogenesis disorder type 1. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in PEX1, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.
