Xq13.1 |
| Allelic Variant 1 |
304040.0003; CHARCOT-MARIE-TOOTH DISEASE, X-LINKED |
| Identified Mutation |
VAL139MET; In a family with X-linked Charcot-Marie-Tooth disease (302800), Bergoffen et al [Science 262: 2039 (1993)] found a G-to-A transition in codon 139 of the CX32 gene, resulting in a substitution of methionine for valine (V139M) in the third transmembrane domain. |
| Remarks |
Clinically affected; hypertrophic variety of CMT disease; diagnosis confirmed by nerve conductivity tests; donor subject is hemizygous for a G>A transition of the GJB1 (Cx32) gene resulting in a substitution of methionine for valine at codon 139 [Val139Met (V139M)]; affected mother is GM04597; affected sister is GM04594; affected niece is GM04595; affected great aunt is GM04596. |
