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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.56C>T (p.T19I) alteration is located in exon 4 (coding exon 2) of the CEP63 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the threonine (T) at amino acid position 19 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 19 of the CEP63 protein (p.Thr19Ile). This variant is present in population databases (rs772285151, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CEP63-related conditions. ClinVar contains an entry for this variant (Variation ID: 2194538). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CEP63 protein function with a negative predictive value of 80%. 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. -
