Double balanced chromosomal translocation carrier (6;8), (13;14)--a case report.

This paper reports the identification of a carrier of two different balanced chromosomal translocations (45,XX,-13,-14, + t(13q;14q), t(6;8) (p11;p12]. Ascertainment occurred during family studies following prenatal diagnosis performed because of advanced maternal age. Family pedigree and past reproductive difficulties also are reviewed, and the theoretical probability of producing a phenotypically normal offspring is explored. We are unaware of previously published observations in which two different balanced autosomal translocations are found in the same individual.
