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]

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Jan 22, 2018	The TRIM2 c.1013C>G; p.Thr338Ser variant (rs146686472), to our knowledge, is not reported in the medical literature, gene specific variation databases, nor has it been previously identified by our laboratory. This variant is listed in the genome Aggregation Database (gnomAD) with a non-Finnish European population frequency of 0.04% (identified on 45 out of 126,416 chromosomes) and is classified as a variant of unknown significance in ClinVar (ID: 444644). The threonine at position 338 is moderately conserved, considering 12 species, and computational analyses of the effects of the p.Thr338Ser variant on protein structure and function do not predict a deleterious effect (SIFT: tolerated, MutationTaster: polymorphism, PolyPhen-2: benign). Based on the available information, the clinical significance of the p.Thr338Ser variant cannot be determined with certainty. -

The c.1094C>G (p.T365S) alteration is located in exon 6 (coding exon 6) of the TRIM2 gene. This alteration results from a C to G substitution at nucleotide position 1094, causing the threonine (T) at amino acid position 365 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 338 of the TRIM2 protein (p.Thr338Ser). This variant is present in population databases (rs146686472, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with TRIM2-related conditions. ClinVar contains an entry for this variant (Variation ID: 444644). 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. -
