title: [Partial 11q trisomy due to missegregation of maternal t(11;22) (q23;q11.1) translocation (author's transl)].
abstract: In a 4-month-old female infant with multiple congenital abnormalities karyotyping revealed a 47,XX, + der (22), t (11;22) (q23.1;q11.1) mat pattern, resulting from a maternal translocation, which was also found in other members of the mother's family. The phenotype was consistent with the physical abnormalities described in previously reported cases of partial 11 q trisomy. The apparently high incidence of this type of translocation is surprising.
