We report on a 14-month-old girl with bifid nasal tip and tetralogy of
Fallot. Several similar patients have been described with CNS or eye
abnormalities, Chromosome analysis with FISH, using Oncor DiGeorge pro
bes, confirmed a submicroscopic deletion of 22q11, Many patients with
Shprintzen (velo-cardio-facial) syndrome have a similar deletion with
conotruncal cardiac defects and an abnormal nasal shape, suggesting th
at a gene in this area, possibly affecting neural crest cells, influen
ces facial and other midline development. (C) 1997 Wiley-Liss, Inc.
