A new chromosomal anomaly associated with mature B-cell chronic lymphoproliferative disorders: del(7)(q32).
Among 63 patients with chronic lymphoproliferative disorders (CLPD) studied cytogenetically in our laboratory, four showed a del(7)(q32); in two it was the sole cytogenetic anomaly and in two it was part of a complex karyotype. We suggest that despite the rarity of this anomaly, it could be related to CLPD.
