GeneDx	RCV000424743	SCV000513497	benign	not specified	2015-05-08	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	RCV000364565	SCV000942361	uncertain significance	Charcot-Marie-Tooth disease, type 2	2018-12-06	criteria provided, single submitter	clinical testing	This sequence change affects codon 496 of the LMNA mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the LMNA protein. This variant also falls at the last nucleotide of exon 8 of the LMNA coding sequence, which is part of the consensus splice site for this exon. This variant is present in population databases (rs375516745, ExAC 0.01%). This variant has not been reported in the literature in individuals with LMNA-related conditions. ClinVar contains an entry for this variant (Variation ID: 292839). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
