RCV000458156 | SCV000547864 | uncertain significance | Mitochondrial hypertrophic cardiomyopathy with lactic acidosis due to MTO1 deficiency | 2016-09-21 | criteria provided, single submitter | clinical testing | In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: (SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). The serine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies. While this variant is not present in population databases (rs753873871), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change replaces proline with serine at codon 21 of the MTO1 protein (p.Pro21Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine. |
