Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_153717.3(EVC):c.2457del(p.Met820TrpfsTer108) variant causes a frameshift change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. R819R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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]

Ellis-van Creveld syndrome;C0457013:Curry-Hall syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 31, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 5344). This variant is also known as 2456delG. This premature translational stop signal has been observed in individual(s) with Ellis-van Creveld syndrome (PMID: 10700184). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Met820Trpfs*108) 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). - |
