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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.996C>T variant (rs116558260) has not been reported in the medical literature, and is not listed in gene-specific variant databases. The c.996C>T variant is also listed in the Genome Aggregation Database (gnomAD) browser with an allele frequency of 0.18% in the African population (identified in 43 out of 23,970 chromosomes). The cytosine at nucleotide 996 is weakly conserved, but computational analyses predict that this variant creates a cryptic splice donor site (Alamut software v2.10.0). Therefore, based on the available information, the clinical significance of the c.996C>T variant cannot be determined with certainty. -
