Invitae | RCV002024535 | SCV002316066 | uncertain significance | not provided | 2021-09-15 | criteria provided, single submitter | clinical testing | 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. 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 methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with CEP250-related conditions. This variant is present in population databases (rs551222580, ExAC 0.002%). This sequence change replaces leucine with methionine at codon 1660 of the CEP250 protein (p.Leu1660Met). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and methionine. |
