Genes affected

CNOT1 (HGNC:7877): (CCR4-NOT transcription complex subunit 1) Enables armadillo repeat domain binding activity; molecular adaptor activity; and nuclear receptor binding activity. Contributes to poly(A)-specific ribonuclease activity. Involved in several processes, including negative regulation of signal transduction; positive regulation of cytoplasmic mRNA processing body assembly; and regulation of gene expression. Located in P-body and cytosol. Part of CCR4-NOT complex. Implicated in holoprosencephaly. [provided by Alliance of Genome Resources, Apr 2022]

SETD6 (HGNC:26116): (SET domain containing 6, protein lysine methyltransferase) This gene encodes a methyltransferase that adds a methyl group to the histone H2AZ, which is involved in nuclear receptor-dependent transcription. The protein also interacts with several endogenous proteins which are involved in nuclear hormone receptor signaling. A related pseudogene is located on chromosome 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]
