Invitae | RCV000638163 | SCV000759649 | uncertain significance | Charcot-Marie-Tooth disease, type I | 2019-11-14 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with methionine at codon 143 of the MPZ protein (p.Thr143Met). The threonine residue is moderately conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is present in population databases (rs750724650, ExAC 0.03%). This variant has been reported in an individual affected with Charcot-Marie-Tooth disease (CMT) and has been reported to segregate with CMT in a single family (PMID: 20456450). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

RCV001097625 | SCV001253922 | uncertain significance | Charcot-Marie-Tooth disease, demyelinating, type 1b | 2017-04-28 | criteria provided, single submitter | clinical testing | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. |
