Genes affected

C2CD3 (HGNC:24564): (C2 domain containing 3 centriole elongation regulator) This gene encodes a protein that functions as a regulator of centriole elongation. Studies of the orthologous mouse protein show that it promotes centriolar distal appendage assembly and is also required for the recruitment of other ciliogenic proteins, including intraflagellar transport proteins. Mutations in this gene cause orofaciodigital syndrome XIV (OFD14), a ciliopathy resulting in malformations of the oral cavity, face and digits. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Nov 2014]

The observed missense c.7027C>T(p.Arg2343Trp) variant in C2CD3 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency of 0.009% in the gnomAD Exomes. The amino acid Arg at position 2343 is changed to a Trp changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Arg2343Trp in C2CD3 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The variant is predicted as damaging by SIFT. For these reasons, this variant has been classified as Uncertain Significance. -
