Charcot-Marie-Tooth disease in Molise, a central-southern region of Italy: an epidemiological study.

An epidemiological survey of Charcot-Marie-Tooth disease (CMT) was conducted in Molise, a central-southern region of Italy, from March 1998 to June 2000. Fifty-eight cases of CMT in 13 unrelated families were identified within the selected area. The prevalence of all subtypes of CMT was 17.5/100,000. All families underwent a bio-molecular analysis to disclose the duplication at gene locus 17p11.2 in order to ascertain the diagnosis of CMT type 1A. Our data revealed that 64% of all the observed patients had CMT1A, thus confirming the high prevalence of duplication of the 17p11.2 locus.
