Forkhead box protein E3 (FOXE3) also known as forkhead-related transcription factor 8 (FREAC-8) is a protein that in humans is encoded by the FOXE3 gene located on the short arm of chromosome 1.[2]


FOXE3 is a forkhead-box transcription factor which is involved in the proper formation of the ocular lens and is post-natally expressed in the lens epithelium.

Clinical significance[edit]

Mutations in the FOXE3 gene are associated with anterior segment mesenchymal dysgenesis.[3]

Homozygous mutations in this gene have been associated with a number of ocular diseases such as congenital aphakia,[4][5] sclerocornea, microphthalmia, and optic disc coloboma.[6] There have also been reports of heterozygous mutations causing less severe ocular diseases such as anterior segment dysgenesis (sometimes referred to as anterior segment mesenchymal dysgenesis),[3] and Peter's anomaly.[7]
