List genes that have been found mutated in CMT1A (Charcot-Marie-Tooth disease type 1 A).
['Most cases of CMT are caused by mutations in PMP22,', ' structural myelin protein PMP22', 'Duplication of the gene encoding the peripheral myelin protein of 22 kDa (PMP22) underlies the most common inherited neuropathy, Charcot-Marie-Tooth 1A (CMT1A), a disease without a known cure.', '. Two patients showed rearrangements in the PMP22 gene, which is commonly associated with CMT1', 'Many PMP22 mutants accumulate in excess in the endoplasmic reticulum (ER) and lead to the inherited neuropathies of Charcot-Marie-Tooth (CMT) disease. ', 'The T118M mutation in PMP22 gene is associated with Charcot Marie Tooth, type 1A (CMT1A).', 'In CMT1, PMP22 duplication was the most common mutation while the second gene in order of frequency was MPZ in familial and SH3TC2 in isolated cases. ', 'CMT1A/PMP22 duplication', 'he most frequent subtype is type 1A (CMT1A) caused by duplication in chromosome 17p12 that includes PMP22.']
