GeneDx RCV000118013 SCV000171098 benign not specified 2011-09-15 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Wong Mito Lab, Molecular and Human Genetics, Baylor College of Medicine RCV000464149 SCV000887078 benign Progressive sclerosing poliodystrophy 2018-10-01 criteria provided, single submitter clinical testing The NM_002693.2:c.2254C>T (NP_002684.1:p.Leu752=) [GRCH38: NC_000015.10:g.89323415G>A] variant in POLG gene is interpretated to be a Benign based on ACMG guidelines (PMID: 25741868). This variant meets the following evidence codes reported in the ACMG-guideline. BS1:The minor allele frequency of this allele is high for Mitochondrial DNA depletion syndrome 4A (Alpers type). BS2:Observation of the variant in controls is inconsistent with penetrance of Mitochondrial DNA depletion syndrome 4A (Alpers type). BP4:Computational evidence/predictors indicate no impact on the POLG structure, function, or protein-protein interaction. Based on the evidence criteria codes applied, the variant is suggested to be Benign.
