We read with interest the report of Robin et al. [1995] published in recent issue of the Journal. The authors described 6 patients with Noonan syndrome (NS) who underwent molecular evaluation for submicroscopic deletion of chromosome band 22q11. None of those patients presented with conotruncal heart defects. Evidence for 22q11 hemizygosity was demonstrated in only one patient. This patient had NS-like manifestations without clinical manifestations of DiGeorge (DG) or velo-cardio-facial (VCF) syndromes. The molecular results obtained in the other 5 patients led the authors to conclude that classical NS is not due to del(22)(q11), even if some patients with del(22)(q11) may present NS-like manifestations. 12 refs., 1 tab.
