Ataxia with telangiectasia is a rare form ataxia that causes chromosomal instability, sensitivity to ionizing radiation, disrupted stress-activated signal transduction pathways and radioresistant DNA synthesis. [5] The genes that underlie majority of the symptoms for the different types of ataxia are still unknown.

Blepharospasm may occur as secondary to conditions including dry eyes and other specific ocular disease or conditions, Meige's syndrome and other forms of dystonia, and Parkinson's disease and other movement disorders.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

Many factors, including genetic factors, hypoxia, oxidative stress, and inflammatory stressors, may cause pathologic over-production of VEGF by the RPE. This over-production causes excess blood vessel formation in the choroid region (the choriocapillaris), which is a major cause of wet AMD. [109]
