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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0028414726).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0174 (2644/152218) while in subpopulation NFE AF = 0.0289 (1963/68016). AF 95% confidence interval is 0.0278. There are 30 homozygotes in GnomAd4. There are 1203 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 2644 AD gene.
