A study on a family with high incidence of leukemia.
A family with a high incidence of leukemia was investigated and followed up for 10 years. Up to now, 7 of 48 members in this family had acute nonlymphocytic leukemia. Chromosomal aberration was found in 3 healthy members, 2 of whom were found to have 47, XX, +5, -8, +Mar, del (7) (q22-qter) and 45, XO, -Y chromosomes and developed this disease 5 and 7 years later respectively. Pedigree analysis suggested that the hereditary defect in the family should rest on the maternal lineage. It is considered that hereditary factors play an important part in the pathogenesis of leukemia in the family.
