title: Estimation of the male to female ratio of mutation rates from the segregation of X-chromosomal DNA haplotypes in Duchenne muscular dystrophy families.
abstract: A novel procedure is presented to estimate the ratio of male to female mutation rates for Duchenne muscular dystrophy (DMD). X-specific restriction fragment length polymorphisms are used to establish DNA haplotypes in three-generation DMD families. From the proportion of DMD patients who have inherited their maternal grandfather's X chromosome, the ratio of mutation rates can be calculated. In contrast to classical methods, the proposed procedure is not restricted to sporadic or familiar cases nor is any information on the carrier status of female relatives required.
