Charcot-Marie-Tooth disease type 2P

Disease Overview

Charcot-Marie-Tooth disease type 2P (CMT2P) is a subtype of Charcot-Marie-Tooth caused by changes (mutations) in the LRSAM1 gene. The onset of symptoms commonly occurs between 20 and 40 years of age and the disease seems to be relatively mild and benign. Symptoms may include mild loss of sensation in the fingertips and severe loss of sensation in the feet and legs. The most common type of sensation loss is to vibration, but proprioception (the sense of how we are oriented in space) and perception to pain may also be affected. Individuals with CMT2P may also have muscle twitches (fasciculations) and cramps (in younger patients) and muscular weakness and muscular wasting in the legs, feet and hands (in older individuals). It may be inherited in an autossomal dominant or autossomal recessive pattern.[9186][9187]
