Chondrodysplasia punctata in an infant with duplication 16p due to a 7;16 translocation.

This paper describes a newborn with a number of clinical manifestations compatible with duplication 16p due to a 46, XY, -7, +der (7), t(7;16) (p22;p13) pat karyotype. In addition, the baby had chondrodysplasia punctata, whose distribution of lesions did not match any of the well-documented forms of these disorders. The baby also had microcornea and lacked a gallbladder, two features, in addition to chondrodysplasia punctata, that have not previously been noted in cases of duplication 16p.
