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]

Collection Method: clinical testing

The c.21G>T (p.E7D) alteration is located in exon 2 (coding exon 1) of the CNOT6 gene. This alteration results from a G to T substitution at nucleotide position 21, causing the glutamic acid (E) at amino acid position 7 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
