Cytogenetic examinations of a 7/12-year-old girl and her parents revealed a familial G/G translocation.

46 chromosomes in the mitoses of the mongoloid child and only 45 chromosomes in those of the apparently normal father could be observed. The analysis of karyotypes revealed a balanced G/G translocation in the father and a G/G translocation mongolism in the probanda. Dermatoglyphic patterns of both the child and her father showed some features characteristic of Down's syndrome.

The mother's karyotype proved to be normal (46, XX).
