Genes affected

GABPB1 (HGNC:4074): (GA binding protein transcription factor subunit beta 1) This gene encodes the GA-binding protein transcription factor, beta subunit. This protein forms a tetrameric complex with the alpha subunit, and stimulates transcription of target genes. The encoded protein may be involved in activation of cytochrome oxidase expression and nuclear control of mitochondrial function. The crystal structure of a similar protein in mouse has been resolved as a ternary protein complex. Multiple transcript variants encoding distinct isoforms have been identified for this gene.

RNU6-94P (HGNC:47057): (RNA, U6 small nuclear 94, pseudogene)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.0).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.561 is higher than 0.05.
