RCV001207572 | SCV001378934 | uncertain significance | Nephronophthisis 15 | 2022-10-24 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 890 of the CEP164 protein (p.Arg890His). This variant is present in population databases (rs368178224, gnomAD 0.08%). 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: 938369). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CEP164 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

| Ambry Genetics | RCV004033703 | SCV004925795 | uncertain significance | Inborn genetic diseases | 2023-11-06 | criteria provided, single submitter | clinical testing | The c.2669G>A (p.R890H) alteration is located in exon 21 (coding exon 19) of the CEP164 gene. This alteration results from a G to A substitution at nucleotide position 2669, causing the arginine (R) at amino acid position 890 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV004753231 | SCV005366177 | uncertain significance | CEP164-related disorder | 2024-08-20 | no assertion criteria provided | clinical testing | The CEP164 c.2669G>A variant is predicted to result in the amino acid substitution p.Arg890His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.081% of alleles in individuals of African descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
