Fetal Onset Neuroaxonal Dystrophy
Body function: Muscle & Neurological
Fetal onset neuroaxonal dystrophy (FNAD) is a genetic neuromuscular disorder in Giant Schnauzers caused by a mutation in the MFN2 gene. This condition disrupts the function of motor nerve cells, leading to severe underdevelopment of muscles and organs in affected puppies. The disorder is autosomal recessive.
