Category Biochemistry
Test background

Deficiency of this enzyme is one of the rarer, non-classic, causes of galactosaemia. The classic form of galactosaemia is associated with galactose-1-phosphate uridyltransferase (G1PUT) deficiency. Like G1PUT deficiency, galactokinase deficiency causes cataracts in the neonatal period, but the early systemic effects of galactokinase deficiency are less severe.

Clinical Indications

Do not test unless the common form of galactosaemia has been eliminated from diagnosis.
