RT Journal Article SR Electronic T1 The use of linked DNA polymorphisms for genotype prediction in families with Duchenne muscular dystrophy. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 252 OP 254 DO 10.1136/jmg.20.4.252 VO 20 IS 4 A1 P S Harper A1 T O'Brien A1 J M Murray A1 K E Davies A1 P Pearson A1 R Williamson YR 1983 UL http://jmg.bmj.com/content/20/4/252.abstract AB Two DNA restriction fragment length polymorphisms show genetic linkage to the Duchenne muscular dystrophy locus on the short arm of the X chromosome. Examples are given of families in which these polymorphisms can be used in the prediction of genotype for this disorder.
