A family with three brothers presenting 12p trisomy due to an adjacent-1 segregation of a paternal translocation (1;12) (q44;p12.2) is described. The patient's phenotype was compatible with the chromosomal imbalance including the gene dosage effect of the glyceraldehyde-3-phosphate dehydrogenase. The importance of the genetic counseling in these families is stressed.
