Guest guest Posted October 30, 2007 Report Share Posted October 30, 2007 Hi , Type 2 CMT is axonal - meaning the problem is within the nerve itself, unlike Type 1 which is a problem with the myelin (wrapping around the nerve) 'Recessive' means the mode of genetic inheritance. This means both parents have to be " carriers " of the CMT gene before a child can be affected. Neither parent has signs of any symptoms of CMT, but the child who inherits autosomal recessive CMT can get a double dose of the defective gene. 2 parents each with an autosomal recessive CMT gene have a 1 in 4 chance of passing it on to their children. Here's a link of the types, and genetic markers. http://www.neuro.wustl.edu/neuromuscular/time/hmsn.html Gretchen Quote Link to comment Share on other sites More sharing options...
