Genes affected

EVC (HGNC:3497): (EvC ciliary complex subunit 1) This gene encodes a protein containing a leucine zipper and a transmembrane domain. This gene has been implicated in both Ellis-van Creveld syndrome (EvC) and Weyers acrodental dysostosis. [provided by RefSeq, Jul 2008]

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 978 of the EVC protein (p.Asp978Asn). This variant is present in population databases (rs150173231, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with EVC-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; 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. -
