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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-117381864-C-T is Pathogenic according to our data. Variant chr11-117381864-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 37297.Status of the report is criteria_provided_single_submitter, 1 stars.

ClinVar contains an entry for this variant (Variation ID: 37297). This sequence change creates a premature translational stop signal (p.Gln525*) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with nephronophthisis-related ciliopathies (PMID: 22863007). For these reasons, this variant has been classified as Pathogenic. -
