The study is published in today's online issue of Nature as a collaboration between some of the nation's top institutions and Mayo Clinic 's Center for Regenerative Medicine.
Also, most mitochondrial diseases caused by nDNA mutations (including Leigh syndrome, MNGIE and even MDS) are autosomal recessive, meaning that it takes mutations in both copies of a gene to cause disease. Unlike nDNA, mtDNA passes only from mother to child. Thatâs because during conception, when the sperm fuses with the egg, the spermâs mitochondria â and its mtDNA â are destroyed. Thus, mitochondrial diseases caused by mtDNA mutations are unique because theyâre inherited in a maternal pattern (see illustration below).
