Genetic mutations described both in the work of Saporta et al 9 and in Spanish patients are shown in bold see text for details, especially in relation to the priorities of molecular study. The answer may be obvious when the family survey shows a lineage with affected ancestors, suggesting AD or gender-linked inheritance when there is no male-to-male transmission. Winged scapula Backpack palsy. CMT2 with optic atrophy. A physical exam will be done. J Neurol. Retrieved 7 May In general, sensory symptoms are restricted to decrease in vibratory sense.

Diagnosis You may be asked about your symptoms and health history. A novel recessive Nefl mutation causes a severe, early-onset axonal neuropathy. There is no place for the indiscriminate use of diagnostic CMT genetic panels.

Neurological examination at the age of 9 years revealed slight motor deficit in the lower limbs, particularly in the feet, and generalized hyporeflexia. Se the great majority of CMT cases, mutations involve a reduced number of genes, namely: Charcot-Marie-Tooth disease can be divided into two types: Muscle Nerve, 12pp.
