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]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Mar 08, 2023	For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 551674). This premature translational stop signal has been observed in individuals with Ellis-van Creveld syndrome (PMID: 17024374, 19810119). This variant is present in population databases (rs527255616, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Glu292*) in the EVC gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EVC are known to be pathogenic (PMID: 23220543). -
