We here report linkage studies in a family suffering from a recently described hereditary muscle disease named X-linked myopathy with excessive autophagy (XMEA). Significant lod scores excluding linkage to the Duchenne-Becker muscular dystrophy locus were found. Several other loci on the short and long arms of the X chromosome produced negative lod scores, whereas probe DX13-7 defining locus DXS15 showed no recombinants and a lod score of z = 0.903 at theta = .0. Further studies should be done to determine whether the gene for XMEA is (1) located at Xq and (2) caused by a mutation of the Emery-Dreifuss muscular dystrophy gene, which has been assigned to the same region.
