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]

CEP164 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.42).
• BP6: Variant 11-117394931-C-G is Benign according to our data. Variant chr11-117394931-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 260480.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-117394931-C-G is described in Lovd as [Benign]. Variant chr11-117394931-C-G is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-0.642 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00196 (298/152318) while in subpopulation NFE AF= 0.00368 (250/68022). AF 95% confidence interval is 0.0033. There are 0 homozygotes in gnomad4. There are 104 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 14 AR gene
