title: The problem of partial trisomy 22 reconsidered.
abstract: A patient with partial trisomy 22(PT22) is presented. Inheritance is presumed to be due to secondary nondisjunction in her mother, who has a balanced translocation t(11;22)(q25;q13). The problem of the phenotypic heterogeneity observed with this chromosome change is discussed.
