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]

The CEP164 c.20G>A variant is predicted to result in the amino acid substitution p.Arg7His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0046% of alleles in individuals of European (Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1517576). This variant has not been reported in the literature in individuals affected with CEP164-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 7 of the CEP164 protein (p.Arg7His). -
