Treatment and prognosis Unfortunately no effective drug for CMT exists. Treatment is largely supportive with rehabilitation therapy and surgery for skeletal deformities 5. [radiopaedia.org]

The wide range of disease severity and the overlapping of many signs can make pedigree construction and the determination of recurrence risks and prognosis challenging. The only recourse may be genotyping. [disorders.eyes.arizona.edu]
