Expression of GALT in 9p chromosome alterations: assignment of GALT locus to 9cen leads to 9p22.


Determination of activity and electrophoretic mobility of GALT in patients with various chromosome 9 deletions and duplications confirms the assignment of its locus to 9p and suggests its locus is in the segment 9cen leads to p22. Two inversions of 9qh (inv(9)(p11q12)) did not alter GALT expression.
