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]

This sequence change creates a premature translational stop signal (p.Arg4*) in the CEP164 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CEP164 are known to be pathogenic (PMID: 22863007, 28125082, 32367404, 34132027, 34499853). This variant is present in population databases (rs765277720, gnomAD 0.01%). 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: 1064314). For these reasons, this variant has been classified as Pathogenic. -
