Global warming means that Antarctica and Greenland ice sheets are melting and the oceans are expanding. Sea level rises might be more than a metre by 2100. Low-lying areas such as Bangladesh, Florida and the Netherlands face massive flooding.
Mitochondrial Myopathies (MM) Signs and Symptoms. Sometimes these diseases can cause significant weakness in the muscles that support breathing. Mitochondrial encephalomyopathies also may cause brain abnormalities that alter the brainâs control over breathing. Cardiac care.
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).
