The proband was a 22-year-old woman who had two spontaneous abortions in the first trimester of pregnancy. She had a consanguineous marriage with no history of malformation or developmental disorders in the family. Her gynecological examination was normal. Chromosome analysis of the family showed two different katyotypes 46,XYt(1;16)(p22;p13) and 46,XX,t(1;16)(q24;q24) using high-resolution banding (HRB). Proband's family was also examined for chromosome analysis. A t(1;16)(p22;p13) was found in the husband's father and other relatives, and a t(1;16)(q24;q24) translocation in the proband's family. This second tanslocation is not found in her parents. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
