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]

The c.235G>A (p.G79R) alteration is located in exon 4 (coding exon 1) of the TNRC6C gene. This alteration results from a G to A substitution at nucleotide position 235, causing the glycine (G) at amino acid position 79 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
