**Key characteristics:**
* The HADHAP1 gene is located on chromosome 17q21.1.
* It is a pseudogene, meaning that it is not currently encoding a functional protein.
* The gene is expressed in a variety of cell types, including non-pigmented ciliary epithelial cells, plasma cells, Bergmann glial cells, adventitial cells, ependymal cells, epithelial cells of the uterus, meningeal macrophages, muscle cells, and epithelial cells.
**Pathways and functions:**
* The HADHA proteins are involved in the regulation of epithelial cell function.
* They are expressed in cells that are responsible for the maintenance of epithelial integrity, including non-pigmented ciliary epithelial cells, plasma cells, and Bergmann glial cells.
* The proteins also play a role in the regulation of cell migration and differentiation.
* They are involved in the regulation of epithelial cell migration and differentiation, and are also involved in the regulation of cell adhesion.
**Clinical significance:**
* Mutations in the HADHAP1 gene have been linked to a number of human diseases, including cancer and cardiovascular disease.
* Studies of the HADHAP1 gene have also been used to understand the role of epithelial cells in cancer development and progression.
* The development of drugs that target the HADHA proteins is an active area of research.
