Genes affected
RAB28 (HGNC:9768): (RAB28, member RAS oncogene family) This gene encodes a member of the Rab subfamily of Ras-related small GTPases. The encoded protein may be involved in regulating intracellular trafficking. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 9 and X.

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 11, 2021This variant has not been reported in the literature in individuals affected with RAB28-related conditions. This variant is present in population databases (rs201945581, ExAC 0.06%). This sequence change replaces alanine with threonine at codon 196 of the RAB28 protein (p.Ala196Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
