Abstract

We report a family of X-linked recessive bulbospinal muscular atrophy, which was confirmed by DNA analysis. A 68-year-old man had been suffered from slowly progressive general weakness and muscle wasting for 15 years. On examination, He was dysarthric with nasal voice and had facial muscle weakness with involuntary fascicular contractions. The tongue was wasted with fasciculations. All tendon reflexes were absent. He had not sensory disturbances or any signs of pyramidal involvement. He had gynecomastia and had complained of hand tremor. EMG revealed widespread chronic denervation. Nerve conduction studies and histopathological results showed a pattern of motor-sensory neuropathy. There was an abnormal expansion of CAG repeats in the androgen receptor gene. And two his daughters and two sons were performed DNA analysis, which revealed this disease was X-linked recessive inheritance pattern.
