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]

Likely pathogenic, criteria provided, single submitter	clinical testing	3billion	Jan 03, 2022	Same nucleotide change resulting in same amino acid change has been previously reported to be associated with CEP164 related disorder (ClinVar ID: VCV000037296, PMID:22863007, PS1_P). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 22863007, PM3_M). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.624, 3CNET: 0.904, PP3_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000018, PM2_M). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
Pathogenic, no assertion criteria provided	literature only	OMIM	Aug 03, 2012	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Feb 20, 2022	In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this missense change affects CEP164 function (PMID: 25340510). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 37296). This missense change has been observed in individuals with nephronophthisis-related ciliopathies (PMID: 22863007, 27708425). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs387907310, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 93 of the CEP164 protein (p.Arg93Trp). -
