Genes affected
EVC2 (HGNC:19747): (EvC ciliary complex subunit 2) This gene encodes a protein that functions in bone formation and skeletal development. Mutations in this gene, as well as in a neighboring gene that lies in a head-to-head configuration, cause Ellis-van Creveld syndrome, an autosomal recessive skeletal dysplasia that is also known as chondroectodermal dysplasia. Mutations in this gene also cause acrofacial dysostosis Weyers type, also referred to as Curry-Hall syndrome, a disease that combines limb and facial abnormalities. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

Ellis-van Creveld syndrome;C0457013:Curry-Hall syndrome Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingInvitaeDec 24, 2021For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 580714). This variant has not been reported in the literature in individuals affected with EVC2-related conditions. This variant is present in population databases (rs748820015, gnomAD 0.008%). This sequence change creates a premature translational stop signal (p.Ser114*) in the EVC2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EVC2 are known to be pathogenic (PMID: 17024374, 19810119, 19876929). -
