Genes affected

CEP164 (HGNC:29182): (centrosomal protein 164) This gene encodes a centrosomal protein involved in microtubule organization, DNA damage response, and chromosome segregation. The encoded protein is required for assembly of primary cilia and localizes to mature centrioles. Defects in this gene are a cause of nephronophthisis-related ciliopathies. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1354 of the CEP164 protein (p.Asp1354Asn). This variant is present in population databases (rs200520898, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with CEP164-related conditions. ClinVar contains an entry for this variant (Variation ID: 569863). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CEP164 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. -

Collection Method: clinical testing

The c.4060G>A (p.D1354N) alteration is located in exon 30 (coding exon 28) of the CEP164 gene. This alteration results from a G to A substitution at nucleotide position 4060, causing the aspartic acid (D) at amino acid position 1354 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

This patient is homozygous for a variant of unknown clinical significance (VOUS), c.4060G>A p.(Asp1354Asn) in exon 30 of the CEP164 gene. To our knowledge, this variant has not been previously reported in the literature. This variant has been reported in dbSNP (rs200520898) and ESP with a minor allele frequency of 0.05% in a European American population. In silico analysis (Alamut Visual v2.4) using PolyPhen2, SIFT, Align GVGD and Mutation Taster all suggest that this variant does not affect protein function and is likely to be a non-pathogenic variant. Alamut Visual v2.4 also predicts this variant does not affect splicing. However, this analysis alone cannot be used to exclude pathogenicity. -
