Invitae RCV001051424 SCV001215577 uncertain significance Familial aplasia of the vermis 2022-10-13 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 512 of the INPP5E protein (p.Arg512Gln). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with Joubert syndrome (PMID: 27081510). ClinVar contains an entry for this variant (Variation ID: 847803). 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 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.
