Savior Sibling
A Savior Sibling (pronunciation: /ˈseɪvjər ˈsɪblɪŋ/) is a term used in the field of medical ethics and genetics to describe a child who is born to provide an organ or cell transplant to a sibling that is affected by a fatal disease, such as Fanconi anemia or thalassemia.
Etymology
The term "Savior Sibling" is derived from the English words "savior", meaning one who saves or rescues, and "sibling", referring to a brother or sister. The term was coined to describe the specific purpose of these siblings' conception and birth - to save the life of their existing sibling.
