- Cranial nerve involvement has not been reported in CMT4H.
- We report a case of CMT4H with slow progression and cranial nerve involvement.
- A novel c.724C>T mutation was identified in FGD4 gene.
Charcot-Marie-Tooth disease type 4H (CMT4H) is a rare variant of autosomal recessive hereditary neuropathy. It is caused by FGD4 mutations and characterized by early infantile onset, slowly progressive distal muscle weakness, scoliosis, and myelin outfoldings visible in nerve biopsy samples. Here, we report a 65-year-old male born to consanguineous parents, who carries a novel homozygous FGD4 c.724C>T nonsense mutation. He developed lower limb weakness in his teens, which progressed slowly and was accompanied by diplopia, bilateral hearing loss, and erectile dysfunction from his twenties. At the age of 65, he was wheelchair-bound and had mild scoliosis, bilateral ophthalmoplegia, facial muscle weakness, inner ear hearing loss, distal-dominant weakness, and sensory disturbance, but no cognitive deterioration. Magnetic resonance imaging revealed enlarged bilateral trigeminal and facial nerves. Accordingly, we believe that this mutation causes slowly progressive sensorimotor neuropathy with apparent cranial nerve involvement, thereby further expanding the clinical spectrum of CMT4H.
