Limb girdle muscular dystrophy due to LAMA2 mutations: diagnostic difficulties due to associated peripheral neuropathy.

We report an eleven year old girl with early motor difficulties initially diagnosed with a peripheral neuropathy in another hospital based on abnormal electrophysiological findings. Our clinical assessment did not highlight obvious clinical features supporting a peripheral neuropathy but evidence of mild proximal weakness. Electrophysiological studies performed at our hospital revealed evidence of a sensorimotor demyelinating polyneuropathy with possible axonal involvement.
