Genes affected

MIR96 (HGNC:31648): (microRNA 96) 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]

(HGNC:):

not specified Benign:2

Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Dec 06, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Oct 05, 2013	36T>C in Exon 1 of MIR96: This variant is not expected to have clinical signific ance because it has been identified in 0.7% (5/725) of American European and Eur opean chromosomes by the 1000 Genome Project (http://www.1000genomes.org/; dbSNP rs41274239) as well as 0.4% (28/7102) of European American chromosomes from a b road population by the NHLBI Exome Sequencing Project (http://evs.gs.washington. edu/EVS/), and is not located in the seed region of the miRNA. -
