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.557C>T (p.T186I) alteration is located in exon 6 (coding exon 5) of the CNOT6 gene. This alteration results from a C to T substitution at nucleotide position 557, causing the threonine (T) at amino acid position 186 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
