✦ Synopsis
A Bayesian method to predict disease recurrence risks based on distance information between loci and allowing for uncertain gene location is presented. The methodology allows derivation of the posterior distribution of recurrence risks, from which point estimates and associated precision measures can be calculated. The resulting risk distribution accounts for all available information concerning location and relative distance, and can be updated as additional data become available. o

Information on linked markers can greatly improve estimates of recurrence risk for genetic disorders. However, when linkage is incomplete, utilizing the information in genetic counseling requires complex, repetitive calculations to estimate correct risks whenever the parental linkage phase is not pr
We apply a method proposed by Rogatko et al. [1995: Am J Med Genet 59:24-32] to estimate carrier risks using genetic linkage data. The method is illustrated for X-linked ocular albinism. Linkage data from pedigrees were combined with genome mapping data to compute carrier risks for individuals with
