title: [Homozygosity and atypical myeloproliferative syndrome (author's transl)].
abstract: An abnormal clone with four chromosomal rearrangements was found in the bone marrow of a patient with an atypical myeloproliferative syndrome and with an almost exclusive polymorphonuclear hyperplasia in blood: t (4;12), i(17 q),20q--. An heterozygosity for a normal variant of one chromosome No. 3 was observed in blood cell cultures. In bone marrow however both chromosomes No. 3 had the same Q-banding patterns. A mechanism of somatic segregation may explain this partial homozygosity.
