Genes affected

TNRC6A (HGNC:11969): (trinucleotide repeat containing adaptor 6A) This gene encodes a member of the trinucleotide repeat containing 6 protein family. The protein functions in post-transcriptional gene silencing through the RNA interference (RNAi) and microRNA pathways. The protein associates with messenger RNAs and Argonaute proteins in cytoplasmic bodies known as GW-bodies or P-bodies. Inhibiting expression of this gene delocalizes other GW-body proteins and impairs RNAi and microRNA-induced gene silencing. [provided by RefSeq, Jul 2008]

The c.1100A>G (p.H367R) alteration is located in exon 6 (coding exon 6) of the TNRC6A gene. This alteration results from a A to G substitution at nucleotide position 1100, causing the histidine (H) at amino acid position 367 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
