Genes affected

CNOT4 (HGNC:7880): (CCR4-NOT transcription complex subunit 4) The protein encoded by this gene is a subunit of the CCR4-NOT complex, a global transcriptional regulator. The encoded protein interacts with CNOT1 and has E3 ubiquitin ligase activity. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]

The c.2063C>A (p.P688Q) alteration is located in exon 12 (coding exon 11) of the CNOT4 gene. This alteration results from a C to A substitution at nucleotide position 2063, causing the proline (P) at amino acid position 688 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
