Genes affected

RAB11B (HGNC:9761): (RAB11B, member RAS oncogene family) The Ras superfamily of small GTP-binding proteins, which includes the Ras (see MIM 190020), Ral (see MIM 179550), Rho (see MIM 165390), Rap (see MIM 179520), and Rab (see MIM 179508) families, is involved in controlling a diverse set of essential cellular functions. The Rab family, including RAB11B, appears to play a critical role in regulating exocytotic and endocytotic pathways (summary by Zhu et al., 1994 [PubMed 7811277]).[supplied by OMIM, Nov 2010]

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. This variant has not been reported in the literature in individuals affected with RAB11B-related conditions. This variant is present in population databases (rs768804811, gnomAD 0.005%). This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 3 of the RAB11B protein (p.Thr3Ala). -
