title: Deletion of 2p: a cytogenetic and clinical update.
abstract: The locus for acid phosphatase (ACP1) had been alternately assigned to two conflicting regions on the short arm of chromosome 2. We present a clinical and cytogenetic report of one patient who has an interstitial deletion of 2, del(2) (p23p25.1), and a cytogenetic study of another cell line with an interstitial deletion of 2p (p23.1p25.1). Because both patients are heterozygotes for ACP1, the assignment of ACP1 to 2p25.1----pter is supported.
