Genes affected

FUBP3 (HGNC:4005): (far upstream element binding protein 3) Enables single-stranded DNA binding activity. Involved in positive regulation of gene expression; positive regulation of transcription, DNA-templated; and transcription, DNA-templated. Acts upstream of or within positive regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.805

Collection Method: clinical testing

The c.650A>G (p.D217G) alteration is located in exon 8 (coding exon 8) of the FUBP3 gene. This alteration results from a A to G substitution at nucleotide position 650, causing the aspartic acid (D) at amino acid position 217 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
