GeneDx	RCV000438852	SCV000528579	likely benign	not specified	2016-06-10	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.
Invitae	RCV000536584	SCV000657873	uncertain significance	Charcot-Marie-Tooth disease type 4	2018-07-03	criteria provided, single submitter	clinical testing	This sequence change affects codon 462 of the MTMR2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the MTMR2 protein. This variant is present in population databases (rs139369561, ExAC 0.005%) but has not been reported in the literature in individuals with a MTMR2-related disease. ClinVar contains an entry for this variant (Variation ID: 386798). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, this is a rare silent change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance.
