Genes affected

CNOT6 (HGNC:14099): (CCR4-NOT transcription complex subunit 6) This gene encodes the catalytic component of the CCR4-NOT core transcriptional regulation complex. The encoded protein has a 3'-5' RNase activity and prefers polyadenylated substrates. The CCR4-NOT complex plays a role in many cellular processes, including miRNA-mediated repression, mRNA degradation, and transcriptional regulation. [provided by RefSeq, Dec 2014]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.814A>G (p.M272V) alteration is located in exon 8 (coding exon 7) of the CNOT6 gene. This alteration results from a A to G substitution at nucleotide position 814, causing the methionine (M) at amino acid position 272 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
