In short, these goats seize up when they get excited due to a quirk in their genetics, called myotonia congenita .
The reason that fainting goats faint is that they have a hereditary genetic disorder called myotonia congenita.
Vanderbilt University School of Medicine, Nashville, Tennessee, United States of America Myotonic dystrophy types 1 and 2 (DM1 and DM2) are forms of muscular dystrophy that share similar clinical and molecular manifestations, such as myotonia, muscle weakness, cardiac anomalies, cataracts, and the presence of defined RNA-containing foci in muscle nuclei.
Myotonic dystrophy types 1 and 2 (DM1 and DM2) are forms of muscular dystrophy that share similar clinical and molecular manifestations, such as myotonia, muscle weakness, cardiac anomalies, cataracts, and the presence of defined RNA-containing foci in muscle nuclei.
The names refer specifically to myotonia congenita, a condition in which the muscle cells experience prolonged contraction when the goat is startled.
He had been labeled with a number of interesting diagnoses, such as chorea, epilepsy, myotonia, hysteria, and neurasthenia.
Koch MC, Lehmann-Horn F, Pongratz D, Otto M, et al. (1994) Proximal myotonic myopathy: a new dominant disorder with myotonia, muscle weakness, and cataracts.
Despite the different expansions within two apparently unrelated genes, both diseases share many common clinical manifestations, including myotonia, muscle weakness, cataract development, insulin resistance, and cardiac conduction defects.
This is unlikely to be caused by muscular fatigue or myotonia for the following reasons.
Mbnl1 −/− mice display skeletal myotonia, muscle weakness, cataracts and possibly heart disease
