Chromodomain-helicase-DNA-binding protein 4 is an enzyme that in humans is encoded by the CHD4 gene.^[5][6][7] CHD4 is the core nucleosome-remodelling component of the Nucleosome Remodelling and Deacetylase (NuRD) complex.^[8][9][10]

Function

The product of this gene belongs to the SNF2/RAD54 helicase family. It represents the main component of the nucleosome remodeling and deacetylase complex and plays an important role in epigenetic transcriptional repression. Patients with dermatomyositis develop antibodies against this protein.^[7]

Interactions

CHD4 has been shown to interact with HDAC1,^[11][12][13] Histone deacetylase 2,^[13][14][15] MTA2,^[11] SATB1^[16] and Ataxia telangiectasia and Rad3 related.^[15]

Clinical

Mutations in this gene have been associated with a condition known as Sifrim-Hitz-Weiss syndrome.^[17] This condition is characterized by

• Brain anomalies
• Macrocephaly
• Deafness
• Ophthalmic abnormalities
• Dysmorphic features
• Congenital heart defects
• Hypogonadism in males
• Skeletal and limb anomalies
• Global developmental delay
• Mild to moderate intellectual disability
