Increases in blood galactose (Gal) are also observed in other conditions, however: in the relatively rare galactokinase (GALK) deficiency, which can have serious sequelae; in partial GALT deficiency, which has no clinical consequences; and in UDP-galactose-4-epimerase (GALE) deficiency, which has 1 common benign form and 1 extremely rare untreatable form with severe clinical outcomes (2, 3).
