Petrovsky National Research Centre of Surgery, The Federal Agency for Scientific Organizations RCV000677300 SCV000803378 likely pathogenic Dilated cardiomyopathy 1A 2018-08-11 criteria provided, single submitter research
Invitae RCV001384174 SCV001583561 pathogenic Charcot-Marie-Tooth disease type 2 2020-08-27 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Glu372 amino acid residue in LMNA. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in individual(s) with dilated cardiomyopathy and conduction disease (https://cardiovascular.elpub.ru/jour/article/view/420/436). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 559576). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with aspartic acid at codon 372 of the LMNA protein (p.Glu372Asp). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and aspartic acid.
