✦ Synopsis
Wolf-Hirschhorn Syndrome (WHS) is caused by distal deletion of the short arm of chromosome 4 and is characterized by growth de®ciency, mental retardation, a distinctive, `greek-helmet' facial appearance, microcephaly, ear lobe anomalies, and sacral dimples. We report a family with a balanced chromosomal translocation 4;18(p15.32;p11.21) in the father and an unbalanced translocation resulting in partial monosomy 4 and partial trisomy 18 in one living boy and a prenatally diagnosed male fetus. Both showed abnormalities consistent with WHS and had in addition aplasia of one umbilical artery. Karyotyping of another stillborn fetus revealed a supernumerary derivative chromosome der(18)t(4;18)(p15.32;p11.21) of paternal origin and two normal chromosomes 4. The umbilical cord had three normal vessels. A third stillborn fetus with the same balanced translocation as the father had a single umbilical artery and hygroma colli.

We present a prenatal diagnosis of a de novo homologous Robertsonian translocation involving both chromosomes 15. Amniocentesis was performed on a 36-year-old woman at 16.5 weeks of gestation. Chromosome analysis documented a 45,XX,der(15;15) (q10;q10) chromosome pattern. No evidence of a deletion w
