Genes affected

CEP63 (HGNC:25815): (centrosomal protein 63) This gene encodes a protein with six coiled-coil domains. The protein is localized to the centrosome, a non-membraneous organelle that functions as the major microtubule-organizing center in animal cells. Several alternatively spliced transcript variants have been found, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	Dec 06, 2013	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jun 13, 2022	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 128711). This variant has not been reported in the literature in individuals affected with CEP63-related conditions. This variant is present in population databases (rs200994552, gnomAD 0.2%). This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 2 of the CEP63 protein (p.Glu2Val). -

The c.5A>T (p.E2V) alteration is located in exon 3 (coding exon 1) of the CEP63 gene. This alteration results from a A to T substitution at nucleotide position 5, causing the glutamic acid (E) at amino acid position 2 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
