OBJECTIVE: To study the inheritance of the X-linked lymphoproliferative disease (XLP) locus in a German family. DESIGN: Haplotype segregation analysis. SETTING: Departments of Pediatrics and Human Genetics, University of Würzburg and University of Ulm, Federal Republic of Germany. PARTICIPANTS: Fourteen members of a family with XLP. INTERVENTIONS: None. MEASUREMENTS/MAIN RESULTS: Using molecular genetic techniques, we diagnosed the XLP status of the members of a German family. Restriction fragment length polymorphism analysis with closely linked polymorphic X-chromosomal DNA markers (Xq25-q27) revealed XLP carrier status in a female infant. Moreover, the XLP mutation was suggested to have occurred in the germ cell of the grandfather. CONCLUSION: This is the first report of a paternally inherited XLP mutation. The recurrence risk for germ cell mosaicism in XLP may be similar to that of X-linked Duchenne muscular dystrophy.
