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]

Ambry Genetics

Apr 22, 2022

The c.635G>A (p.R212Q) alteration is located in exon 6 (coding exon 6) of the TNRC6A gene. This alteration results from a G to A substitution at nucleotide position 635, causing the arginine (R) at amino acid position 212 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
