Invitae RCV001316706 SCV001507339 uncertain significance Joubert syndrome 15 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces alanine with threonine at codon 354 of the CEP41 protein (p.Ala354Thr). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and threonine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with CEP41-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine 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.
