Abstract
The authors have studied a series of 23 DiGeorge syndrome patients by prometaphase chromosome analysis and/or by FISH with a set of 6 cosmid probes spanning the previously described commonly deleted region. Fou r patients display a cytogenetically visible interstitial deletion in band 22q11.2, whereas the other 18 patients exhibit a molecular deleti on evidenced only by FISH analysis. For 21 of the patients studied, th e deletion encompasses the 6 loci tested, while for one, only the most telomeric of these loci is conserved. The last patient does not show any deletion with the probes used.
