A familial X-autosome translocation with the breakpoint in the "critical region".
We report a case of an X-autosome translocation t(X;4)(q13;p16) found in both sexes in three generations. The anomaly was diagnosed in a couple referred for cytogenetic investigation as a result of three spontaneous abortions. With the exception of the miscarriages there are no particularities in the gynecologic data of the woman or in the pedigree. In all 50 lymphocytes and in 66 of 68 fibroblasts investigated the normal X chromosome was the late replicating one.
