Charcot-Marie-Tooth disease type 4C4 caused by a novel Pro153Leu substitution in the GDAP1 gene.
Charcot-Marie-Tooth type 4C4 disease (CMT4C4) is an early onset, autosomal recessive neuropathy with hoarseness caused by mutations in the GDAP1 gene which maps to the 8q13 region. To date, only 24 mutations in the GDAP1 gene have been reported. Neuropathological findings of sural nerve biopsies have been published for a limited number of CMT4C4 patients. Herein, a novel Pro153Leu mutation in the GDAP1 gene identified in a consanguineous Polish family is described and longitudinal clinical and electrophysiological studies as well as morphological findings are presented.
