Hereditary neuralgic amyotrophy is a type of nervous system disease that affects the brachial plexus. Common signs and symptoms include episodes of severe pain and muscle wasting in one or both shoulders and arms.  Attacks may be spontaneous or triggered (e.g., by exercise, childbirth, surgery, infection etc.).  Secondary complications, such as decreased sensation, abnormal sensations (e.g., numbness and tingling), chronic pain, and impaired movement may develop overtime. Affected members in some families may share additional distinct physical and facial characteristics. Hereditary neuralgic amyotrophy can be caused by mutations in the SEPT9 gene.  It is inherited in an autosomal dominant fashion.[1]
