Genes affected

MIR31HG (HGNC:37187): (MIR31 host gene) This gene produces a long non-coding RNA that acts as a host gene for miR-31. This transcript may be involved in cellular pluripotency and regulate the differentiation of myoblasts and other tissues. This RNA was found to interact with Polycomb repressive proteins to repression transcription of genes involves in cell senescence. [provided by RefSeq, Dec 2017]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.133 is higher than 0.05.
