Genes affected

MIR100HG (HGNC:39522): (mir-100-let-7a-2-mir-125b-1 cluster host gene) This gene produces long non-coding RNAs that act as regulators of cell proliferation. Alternative promoter usage and splicing results in multiple transcript variants. Some transcript variants may promote growth, while others may act to negatively regulate cell division.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.385 is higher than 0.05.
