RT Journal Article SR Electronic T1 Paternal inheritance of translocation chromosomes in a t(X;21) patient with X linked muscular dystrophy. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 491 OP 493 DO 10.1136/jmg.23.6.491 VO 23 IS 6 A1 V M Kean A1 H L Macleod A1 M W Thompson A1 P N Ray A1 C Verellen-Dumoulin A1 R G Worton YR 1986 UL http://jmg.bmj.com/content/23/6/491.abstract AB A number of DNA probes from the short arm of the X chromosome have been used to study the inheritance of the translocation chromosomes in a girl with an X; autosome translocation and muscular dystrophy. The two translocation chromosomes were found to be derived from the father's single normal X chromosome, ruling out maternal inheritance of a pre-existent mutation and enhancing the concept that the de novo translocation is responsible for the dystrophic phenotype.
