Variant summary

Our verdict is The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NR_171007.1(MIR1-1HG):n.788-179G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: NR_171007.1 is not a MANE Select or MANE Plus Clinical transcript for MIR1-1HG; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant allele was found at a cumulative frequency of 0.232 (AC=84,166) in the gnomAD database across 363,416 control chromosomes, including 10,295 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.337. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

MIR1-1HG (HGNC:16159): (MIR1-1 host gene)

MIR1-1HG links:

MIR133A2 (HGNC:31518): (microRNA 133a-2) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]
