Genes affected

IFNA13 (HGNC:5419): (interferon alpha 13) Predicted to enable cytokine activity and type I interferon receptor binding activity. Predicted to be involved in several processes, including B cell activation; lymphocyte activation involved in immune response; and positive regulation of peptidyl-serine phosphorylation of STAT protein. Predicted to be located in extracellular region. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

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

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.29212868).
