FGFR3: Gene involved in bone development.


UCP1: Gene involved in the regulation of body temperature.


ABCG2: This gene codes for a protein which actively extrudes a wide variety of physiological compounds, and dietary toxins from cells.


HTT: This gene is associated with Huntingtons disease, a particularly serious neurodegenerative disease.

chromosome scaffolding

H2AFZ: This is one of the numerous genes that code for histone proteins. The characteristic architecture of a chromosome is due to the way DNA is wound around histones.


This region carries no genes


ADH: This gene is essential for alcohol detoxication.
