In general, the frequency of a given mutation increases in proportion to the dose of radiation in the low-to-intermediate dose range. WebPARK2: The PARK2 gene makes the protein parkin, which normally helps cells break down and recycle proteins. PARK7: Mutations in this gene cause a rare form of early-onset Parkinson’s disease. The PARK7 gene makes the protein DJ-1, which protects against mitochondrial stress. PINK1: The protein made by PINK1 is a protein kinase that protects ...

WebWerner’s syndrome, also known as adult progeria, is a rare inherited disorder that affects various body systems, including the skin, eyes, nervous system, and heart. This condition is caused by mutations in the WRN gene that codes for a protein called WRN helicase, which plays a crucial role in DNA repair and maintenance. WebHereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life.
