title: Familial chromosome translocation t(3;18)(p21;p11).
abstract: A familial translocation t(3;18)(p21;p11) was observed in a newborn male. He had multiple malformations resulting from partial trisomy 3 and partial monosomy 18. The mother, maternal uncle, and maternal grandmother were found to be balanced translocation carriers. A daughter of the maternal uncle with similar malformations probably had the same unbalanced karyotype as the proband.
