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]
CRMP1 (HGNC:2365): (collapsin response mediator protein 1) This gene encodes a member of a family of cytosolic phosphoproteins expressed exclusively in the nervous system. The encoded protein is thought to be a part of the semaphorin signal transduction pathway implicated in semaphorin-induced growth cone collapse during neural development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 28, 2023This sequence change creates a premature translational stop signal (p.Ala565Valfs*23) 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). This variant is present in population databases (rs753014919, gnomAD 0.02%). This premature translational stop signal has been observed in individuals with Ellis-van Creveld syndrome (PMID: 17024374, 23220543). ClinVar contains an entry for this variant (Variation ID: 551227). For these reasons, this variant has been classified as Pathogenic. -
