Genes affected

STUB1 (HGNC:11427): (STIP1 homology and U-box containing protein 1) This gene encodes a protein containing tetratricopeptide repeat and a U-box that functions as a ubiquitin ligase/cochaperone. The encoded protein binds to and ubiquitinates shock cognate 71 kDa protein (Hspa8) and DNA polymerase beta (Polb), among other targets. Mutations in this gene cause spinocerebellar ataxia, autosomal recessive 16. Alternative splicing results in multiple transcript variants. There is a pseudogene for this gene on chromosome 2.

JMJD8 (HGNC:14148): (jumonji domain containing 8) Involved in several processes, including positive regulation of I-kappaB kinase/NF-kappaB signaling; positive regulation of sprouting angiogenesis; and regulation of glycolytic process. Located in endoplasmic reticulum lumen and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.06662971).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000462 (67/1451186) while in subpopulation AMR AF= 0.000158 (7/44370). AF 95% confidence interval is 0.0000733. There are 0 homozygotes in gnomad4_exome. There are 34 alleles in male gnomad4_exome subpopulation. Median coverage is 33.

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 182 of the STUB1 protein (p.Arg182Gln). This variant is present in population databases (rs145094142, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with STUB1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1980459). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt STUB1 protein function with a negative predictive value of 80%. 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. -
