The inwards spiral and especially the elbow contractures are less severe than in LCCS1<unk> . Some patients have intrauterine long bone fractures. Skeletal muscles are affected and show neurogenic atrophy. The size and shape of spinal cord at different levels are normal but<unk> <unk>  motoneurons are diminished in number and degenerated.
