If i have melas, will i pass this on to a child i might have in the future?

Yes, if you are.....: Yes, if you are a woman, no, if you are a man. Melas (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) is caused by mutation of mitochondrial dna. Mitochondrial inheritance is strictly maternal, because the mitochondrial of the zygote are supplied by the ovum and not by the sperm.

Female - yes: Women do pass on the mutation.
