601097.0001; CHARCOT-MARIE-TOOTH DISEASE, TYPE 1A |
Identified Mutation |
DUP (17p); Lupski et al [Cell 66: 219 (1991)] found a DNA duplication as the apparent basis of CMT1A [Charcot-Marie-Tooth Disease, Type 1a (118220)]. The duplication was demonstrated in locus D17S122 (probe VAW409R3). |
Remarks |
Clinically affected; hypertrophic neuropathy; palpable nerves in neck and elbow; high arch of feet; moderate loss of intrinsic foot muscles; hammer toe deformities; moderate weakness of all ankle related musculature; atrophy and weakness distally; decreased sensation; affected family members include 2 siblings, mother, 6 maternal aunts and uncles, and maternal grandfather; affected mother is GM05146; muscle biopsy demonstrated neuropathy; donor subject was found to have a duplication (17p) of the PMP22 gene by MLPA; no mutations were found in the MPZ gene; donor subject also has a homozygous polymorphism: IVS3+64T>C (rs6674383); same subject as GM28252 (iPSC) and GM05149 (lymphocyte) |
