Elongator complex protein 4

Gene

ELP4

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts as subunit of the RNA polymerase II elongator complex, which is a histone acetyltransferase component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. Elongator may play a role in chromatin remodeling and is involved in acetylation of histones H3 and probably H4.3 Publications

Involvement in diseasei

Aniridia 2 (AN2)1 Publication
The disease is caused by mutations affecting the gene represented in this entry. A disease-causing mutation is located in intron 9 of ELP4. The mutation does not alter normal ELP4 expression and function, but disrupts a long-range cis-regulatory element of PAX6 expression, known as SIMO. SIMO is contained within ELP4 intron 9 and located 150 kb downstream of PAX6.1 Publication
Disease descriptionA form of aniridia, a congenital, bilateral, panocular disorder characterized by complete absence of the iris or extreme iris hypoplasia. Aniridia is not just an isolated defect in iris development but it is associated with macular and optic nerve hypoplasia, cataract, corneal changes, nystagmus. Visual acuity is generally low but is unrelated to the degree of iris hypoplasia. Glaucoma is a secondary problem causing additional visual loss over time.
