Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MBNL1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Mediates pre-mRNA alternative splicing regulation. Acts either as activator or repressor of splicing on specific pre-mRNA targets. Inhibits cardiac troponin-T (TNNT2) pre-mRNA exon inclusion but induces insulin receptor (IR) pre-mRNA exon inclusion in muscle. Antagonizes the alternative splicing activity pattern of CELF proteins. Regulates the TNNT2 exon 5 skipping through competition with U2AF2. Inhibits the formation of the spliceosome A complex on intron 4 of TNNT2 pre-mRNA. Binds to the stem-loop structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Binds to the 5'-YGCU(U/G)Y- 3'consensus sequence. Binds to the IR RNA. Binds to expanded CUG repeat RNA, which folds into a hairpin structure containing GC base pairs and bulged, unpaired U residues. {ECO:0000269|PubMed:10970838, ECO:0000269|PubMed:15257297, ECO:0000269|PubMed:16946708, ECO:0000269|PubMed:18335541, ECO:0000269|PubMed:19470458}.;
Disease
DISEASE: Corneal dystrophy, Fuchs endothelial, 3 (FECD3) [MIM:613267]: A late-onset form of Fuchs endothelial corneal dystrophy, a disease caused by loss of endothelium of the central cornea. It is characterized by focal wart-like guttata that arise from Descemet membrane and develop in the central cornea, epithelial blisters, reduced vision and pain. Descemet membrane is thickened by abnormal collagenous deposition. {ECO:0000269|PubMed:25593321}. Note=The protein represented in this entry is involved in disease pathogenesis. In corneal endothelial cells from patients, MBNL1 is sequestered by TCF4 RNAs containing pathogenic CUG triplet repeat expansions. This results in missplicing of essential MBNL1-regulated mRNAs. {ECO:0000269|PubMed:25593321}.;
