Summary
Two infants with dysmorphism and aortic stenosis were trisomic for the distal part of 15q. Similar to seven other published cases, the facial dysmorphism was characteristic: prominent nose, narrow palpebral fissures, slight anti-mongoloïd slant, low-set ears, long upper lip, and a pronounced philtrum. Laboratory studies failed to demonstrate a gene-dose effect for the enzymes coded by chromosome 15 (PK 3 and MPI) and chromosome 21 (SOD 1).
