What causes genetic disorders?Genetics is the science of inheritance. It aims to understand the mechanism by which the blueprints for life are passed through generations and how variations in these blueprints are essential for evolution, yet can cause disease. This article aims to define the major types of genetic disorder and provide exa...
What causes genetic mutations in the brain?Neurological Disorder:A neurological problem is any ailment that affects your brain, spinal cord, or nerves throughout your body. It might be due to a genetic illness, degenerative disorder, developmental disorder, or a disorder caused by an accident....
Achoo syndrome is genetic. The photic sneeze reflex is a genetic trait that causes people to sneeze when exposed to bright light. It is actually a dominant trait. To test this genetic trait, go into a dark room (a bathroom with the lights out, a photo development room, a movie theater)...

While mutations in the genes GBA and LRRK2 represent the two most common genetic causes of Parkinson’s disease, not everyone who has a mutation in one of these genes will develop the disease. This phenomenon, where a mutation can cause disease in some people but not others, is known as...
