Genes affected
TNRC6C (HGNC:29318): (trinucleotide repeat containing adaptor 6C) Predicted to enable RNA binding activity. Involved in gene silencing by miRNA; positive regulation of nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay; and positive regulation of nuclear-transcribed mRNA poly(A) tail shortening. Predicted to be located in cytosol. Predicted to be active in P-body and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
