Wilson's disease liver. It is due to mutations in the "COMMD1" (or "MURR1") gene. Despite this findings, "COMMD1" mutations could not be detected in humans with non-Wilsonian copper accumulation states (such as Indian childhood cirrhosis) to explain their genetic origin. Wilson's disease Wilson's disease is a genetic disorder in which copper builds up in the body. Symptoms are typically related to the brain and liver. Liver related symptoms include vomiting, weakness, fluid build up in the abdomen, swelling of the legs, yellowish skin, and itchiness. Brain related symptoms include tremors, muscle stiffness, trouble speaking, personality changes, anxiety, and seeing or hearing things
Cold and heat adaptations in humans Cold and heat adaptations in humans Cold and heat adaptations in humans are a part of the broad adaptability of "Homo sapiens". Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research on genetic adaptations to cold and heat temperatures. The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F).
