Guest guest Posted June 25, 2003 Report Share Posted June 25, 2003 I found this on the CMT Australia website ~ G Autosomal Recessive CMT Type 4A Usually both parents of an affected child are clinically normal " disease carriers " . This type of CMT is more common in countries where the incidence of marring close relatives is higher. The parents have a 25% recurrence risk to have an affected child. The gene for one of these forms, CMT4A is located on chromosome 8 and it is probable that two other genes can cause Types 4B and 4C although the location of these types is not known. The genetic defect in CMT4A is not yet known. Quote Link to comment Share on other sites More sharing options...
