Invitae | RCV001997796 | SCV002254199 | uncertain significance | not provided | 2023-07-17 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine with glutamine at codon 2228 of the CEP250 protein (p.His2228Gln). The histidine residue is weakly conserved and there is a small physicochemical difference between histidine and glutamine. This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CEP250-related conditions. ClinVar contains an entry for this variant (Variation ID: 1463803). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. |
