Physical findings in 21q22 deletion suggest critical region for 21q- phenotype in q22.

Abstract excerpt

Multiple abnormalities were observed in a newborn infant with a deletion in the long arm of chromosome 21, from band 22q22.1-->qter. The phenotype of this infant was similar to that previously described in infants with deletions spanning the long arm of chromosome 21, from the centromere to 21q22 [Rethoré et al., 1972, Exp Cell Res 70:455-456, 1973, Ann Genet (Paris) 16:271-275].
