Genes affected
RRAS2 (HGNC:17271): (RAS related 2) This gene encodes a member of the R-Ras subfamily of Ras-like small GTPases. The encoded protein associates with the plasma membrane and may function as a signal transducer. This protein may play an important role in activating signal transduction pathways that control cell proliferation. Mutations in this gene are associated with the growth of certain tumors. Pseudogenes of this gene are found on chromosomes 1 and 2. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

Review Status:no assertion criteria provided
Collection Method:clinical testing

The RRAS2 c.439C>T variant is predicted to result in the amino acid substitution p.Arg147Trp. This variant has been reported in the homozygous state in an individual from a cohort of mucopolysaccharidoses patients; however, a second potentially causative variant was also reported in the patient (Family L, Gul et al. 2023. PubMed ID: 37091798). This variant is reported in 0.0054% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
