Submissions by phenotype
not specified Uncertain:1
The c.1349G>A (p.R450Q) alteration is located in exon 6 (coding exon 6) of the TRIM2 gene. This alteration results from a G to A substitution at nucleotide position 1349, causing the arginine (R) at amino acid position 450 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Charcot-Marie-Tooth disease type 2R Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 423 of the TRIM2 protein (p.Arg423Gln). This variant is present in population databases (rs777541972, gnomAD 0.005%). 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: 575222). 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. -
