Deletion 2q: two new cases with karyotypes 46,XY,del(2)(q31q33) and 46,XX,del(2)(q36).

We describe the clinical and cytogenetic findings of two patients with deletions of the long arm of chromosome 2. One has an interstitial deletion identical to that found in a previously reported patient, although they are phenotypically dissimilar. The other patient has a terminal deletion, the first such deletion reported to date.
