Welander distal myopathy – http://id.who.int/icd/entity/1107278535

Welander distal myopathy is a distal, slowly progressive myopathy with late onset (after the age of 40) inherited as an autosomal dominant trait, presenting with clumsiness in performing fine motor skills with the index finger and thumb followed by progression to all the finger extensor muscles and atrophy of intrinsic hand muscles. Lower limb involvement occurs later.
