Genes affected

UBQLN2 (HGNC:12509): (ubiquilin 2) This gene encodes an ubiquitin-like protein (ubiquilin) that shares high degree of similarity with related products in yeast, rat and frog. Ubiquilins contain a N-terminal ubiquitin-like domain and a C-terminal ubiquitin-associated domain. They physically associate with both proteasomes and ubiquitin ligases; and thus, are thought to functionally link the ubiquitination machinery to the proteasome to affect in vivo protein degradation. This ubiquilin has also been shown to bind the ATPase domain of the Hsp70-like Stch protein. [provided by RefSeq, Oct 2009]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 509 of the UBQLN2 protein (p.Pro509Ser). This variant is present in population databases (rs387906712, gnomAD 0.005%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with amyotrophic lateral sclerosis (PMID: 21857683). ClinVar contains an entry for this variant (Variation ID: 29953). Algorithms developed to predict the effect of variants on gene product structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this missense change affects UBQLN2 function (PMID: 25616961, 26075709). 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. -

Review Status: no assertion criteria provided

Collection Method: clinical testing

The UBQLN2 c.1525C>T variant is predicted to result in the amino acid substitution p.Pro509Ser. This variant was reported in an individual with amyotrophic lateral sclerosis (Deng et al. 2011. PubMed ID: 21857683) with functional in vitro studies suggesting this variant impairs protein function (Gilpin et al. 2015. PubMed ID: 25616961; Chang et al. 2015. PubMed ID: 26075709). This variant is reported in 0.0049% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
