Genes affected

TRIM2 (HGNC:15974): (tripartite motif containing 2) The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. The protein localizes to cytoplasmic filaments. It plays a neuroprotective role and functions as an E3-ubiquitin ligase in proteasome-mediated degradation of target proteins. Mutations in this gene can cause early-onset axonal neuropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

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. 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. ClinVar contains an entry for this variant (Variation ID: 582449). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 321 of the TRIM2 protein (p.Thr321Ser). This variant is present in population databases (rs752113810, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with TRIM2-related conditions. -
