TY - JOUR T1 - SCientists probe method to prevent inherited mitochondrial gene diseases AU - Kuehn BM Y1 - 2009/10/07 N1 - 10.1001/jama.2009.1401 JO - JAMA SP - 1409 EP - 1409 VL - 302 IS - 13 N2 - Mutations in mitochondrial DNA occur at a much higher rate than mutations in nuclear DNA and such mutations may frequently be inherited because offspring obtain their mitochondrial DNA almost exclusively from their mother. Other mutated mitochondrial genes may not be inherited but rather emerge during an individual's lifetime. More than 1500 mutations in mitochondrial DNA are associated with serious disease in humans, including myopathies, neurodegenerative disorders, diabetes, cancer, and infertility. There are no cures for such disorders, only treatments that slow the progression of disease, noted Masahito Tachibana, MD, PhD, the first author of the report, in a press conference.
