Abstract excerpt
OBJECTIVE: To demonstrate that intronic mutations in the myelin protein zero (MPZ) cause Charcot-Marie-Tooth neuropathy 1B (CMT1B) by disrupting MPZ splicing. METHODS: We report a family with a T>G transversion at the invariant + 2 position in intron 4 of MPZ (c.614 + 2T>G) that abolishes 5' donor site recognition and is predicted to alter MPZ splicing. We obtained detailed clinical and neurophysiologic analysis...
