Genes affected

BRINP3 (HGNC:22393): (BMP/retinoic acid inducible neural specific 3) This gene is overexpressed in pituitary tumors but is underexpressed in tongue squamous cell carcinomas, ulcerative colitis, and peri-implantitis. Polymorphisms that increase expression of this gene have been shown to increase vascular inflammation, and an association of this gene with myocardial infarction has been demonstrated. Finally, hypermethylation of this gene may find usefulness as a biomarker for gastric cancer. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.65).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.266 is higher than 0.05.
