Note that this will not stop some kids from getting these type of diseases, collectively known as mitochondrial myopathies. Some of them arise sporadically [1] In chronic progressive external ophthalmoplegia (CPEO) — a myopathy with the defining features of ophthalmoplegia and ptosis — Δ-mtDNAs are found only in muscle (implying that the deletion event occurred after fertilization in the muscle lineage of mesoderm). How do I know ? I have a mitocondrial myopathy (CPEO). My mother was perfectly healthy and all my brothers and sisters (5) are also ok.
