chr11-117409675-G-A
Variant summary
Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS1
The NM_014956.5(CEP164):c.3806G>A(p.Arg1269Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000164 in 1,613,920 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1269W) has been classified as Uncertain significance.

Variant summary: CEP164 c.3806G>A (p.Arg1269Gln) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function all suggest that this variant is likely to be tolerated. The variant allele was found at a frequency of 0.0002 in 251226 control chromosomes, predominantly at a frequency of 0.0025 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database exceeds the estimated maximal expected allele frequency for a pathogenic variant in CEP164 causing Nephronophthisis 15 phenotype. To our knowledge, no occurrence of c.3806G>A in individuals affected with Nephronophthisis 15 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 473085). Based on the evidence outlined above, the variant was classified as likely benign. -
CEP164-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
