Genes affected
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]
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.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 23, 2023 | This sequence change falls in intron 4 of the STUB1 gene. It does not directly change the encoded amino acid sequence of the STUB1 protein. It affects a nucleotide within the consensus splice site. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This variant has not been reported in the literature in individuals affected with STUB1-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Experimental studies and prediction algorithms are not available or were not evaluated, and the effect of this variant on mRNA splicing is currently unknown. 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. - |
