Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM1BP4BS2
The NM_013444.4(UBQLN2):c.1474G>C(p.Val492Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000995 in 1,206,568 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 5 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar.

Amyotrophic lateral sclerosis type 15 Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 492 of the UBQLN2 protein (p.Val492Leu). This variant is present in population databases (rs756653207, gnomAD 0.003%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with UBQLN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 448848). 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. -
UBQLN2-related disorder Uncertain:1
The UBQLN2 c.1474G>C variant is predicted to result in the amino acid substitution p.Val492Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0027% of alleles in individuals of European (Non-Finnish) descent in gnomAD, including 1 hemizygote. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
