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]

The EVC2 c.3879_3881del; p.Lys1293del variant (rs752839237), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 550613). This variant is found in the Latino/Admixed American population with an allele frequency of 0.07% (25/35434 alleles) in the Genome Aggregation Database. This variant deletes a single lysine residue leaving the rest of the protein in-frame. Due to limited information, the clinical significance of this variant is uncertain at this time. -
