Genes affected
CNOT2 (HGNC:7878): (CCR4-NOT transcription complex subunit 2) This gene encodes a subunit of the multi-component CCR4-NOT complex. The CCR4-NOT complex regulates mRNA synthesis and degradation and is also thought to be involved in mRNA splicing, transport and localization. The encoded protein interacts with histone deacetylases and functions as a repressor of polymerase II transcription. Alternatively spliced transcript variants have been observed for this gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.158G>A (p.R53Q) alteration is located in exon 3 (coding exon 2) of the CNOT2 gene. This alteration results from a G to A substitution at nucleotide position 158, causing the arginine (R) at amino acid position 53 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
