Gastrointestinal neuromuscular disease
Gene: MIR145
PMID: 36649075- a patient whose fetal ultrasound revealed polyhydramnios, enlarged abdomenand bladder, and prune belly syndrome. During infancy/childhood profound gastrointestinal dysmotility, cerebrovascular disease, and multiple strokes. Described as a multisystemic smooth muscle dysfunction syndrome. Patient was found to have a de novo SNP in MIR145 NR_029686.1:n.18C>A. The MIR145transcript is processed into two microRNAs, with the variant position at nucleotide 3 of miR-145-5p.
Transfection of an siRNA against mutant miR145-5p induced a notable decrease in the expression of several cytoskeletal proteins including transgelin, calponin, and importantly, smooth muscle actin. Hybridization analysis and miR RNA-seq demonstrated a decrease in expression of miR145-5p in the presence of mutant miR145-5p. RNA-seq showed that the differentially expressed genes were substantially different between patient and control fibroblasts.
