Distal Hereditary Motor Neuronopathy Type 2b, also known as neuronopathy, distal hereditary motor, type 2b, is related to neuronopathy, distal hereditary motor, autosomal dominant 3 and distal hereditary motor neuronopathy type 2c. An important gene associated with Distal Hereditary Motor Neuronopathy Type 2b is HSPB1 (Heat Shock Protein Family B (Small) Member 1), and among its related pathways/superpathways is Intracellular trafficking proteins involved in CMT neuropathy. Related phenotypes are peripheral neuropathy and distal lower limb muscle weakness
