Power, bulk, gait, and coordination were intact, but distal hyporeflexia was present. Tinel signs were present at the wrists and elbows. No nerves could be palpated. Hammertoes and high arches were present. [emedicine.medscape.com]
Clinical presentations of RBM have ranged from early onset fatal to childhood onset to adult onset cases. Defects in FHL1 are the cause of X-linked childhood-onset reducing body myopathy (CO-RBM) [MIM:300718]. [abcam.com]
