  • Secondary Myopathy

    We present a family with a distal myopathy secondary to a mutation in myotilin.[] Vitamin B12 level & methylmalonic acid -- deficiencies can affect brain and spinal cord issues that mimic myopathy. CK -- muscle enzyme.[] The myopathy is inhibited by prior sciatic nerve section and is accentuated by cholinesterase inhibition.[]
