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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 16, 2024 | The c.352G>A (p.V118M) 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 352, causing the valine (V) at amino acid position 118 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
