We report on a 16-week-old male fetus with partial trisomy 16 and partial monosomy 22 resulting from 3:3 adjacent-2 segregation of a maternal balanced complex chromosome translocation involving chromosomes 5, 16, and 22. The karyotype of the 29-year-old phenotypically normal mother was 46,XX,t(5;16;22)(q31.3;q12.1;q11.2). The karyotype of the fetus was 46,XY,der (5)t(5;16;22)(q31.3;q12.1;q11.2),+der(16) t(5;16;22)mat,-22. The fetus had multiple congenital anomalies, including bilateral cleft lip and palate.

D002871	Chromosome Banding	Staining of bands, or chromosome segments, allowing the precise identification of individual chromosomes or parts of chromosomes. Applications include the determination of chromosome rearrangements in malformation syndromes and cancer, the chemistry of chromosome segments, chromosome changes during evolution, and, in conjunction with cell hybridization studies, chromosome mapping.
