RT Journal Article SR Electronic T1 A linkage study of a large pedigree with X linked centronuclear myopathy. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 281 OP 283 DO 10.1136/jmg.27.5.281 VO 27 IS 5 A1 J Starr A1 M Lamont A1 L Iselius A1 J Harvey A1 J Heckmatt YR 1990 UL http://jmg.bmj.com/content/27/5/281.abstract AB Centronuclear myopathy (CNM) is a muscle wasting disorder that occurs in three distinct forms. Previous studies have shown linkage between the X linked form of the disease and the Xq28 probes ST14, DX13, and F8C. Our study on a previously unreported, three generation, X linked CNM family confirms linkage between these markers and the CNM locus (Z = 3.21, theta = 00). However, results from the laboratory of J-L Mandel (Samson and Hanover, personal communication) on a number of X linked CNM families exclude genetic linkage from the region Xq26-qter, suggesting genetic heterogeneity in this condition.
