Genes affected

UBP1 (HGNC:12507): (upstream binding protein 1) Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of viral transcription and positive regulation of transcription by RNA polymerase II. Located in cytosol and nucleoplasm.

FBXL2 (HGNC:13598): (F-box and leucine rich repeat protein 2) This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbls class and, in addition to an F-box, contains 12 tandem leucine-rich repeats. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PP2: Missense variant where missense usually causes diseases, UBP1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.846
• BS2: High AC in GnomAd at 10 AD gene.

The c.1499G>T (p.G500V) alteration is located in exon 14 (coding exon 14) of the UBP1 gene. This alteration results from a G to T substitution at nucleotide position 1499, causing the glycine (G) at amino acid position 500 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
