    Red cell triose phosphate isomerase was determined, together with other enzymes, in three patients with chromosome 12 abnormalities. In patient No. 1 (trisomy of the segment 12pter -> 12q12) and in patient No. 2 (trisomy of the segment 12pter -> 12p121), the TPI activity was significantly increased. In patient No. 3 (deletion of the segment 12p11 -> 12p122) the TPI activity was in the normal range. It is suggested that the human TPI locus is located on the chromosome 12 short arm between 12pter and 12p122.
