GALT and galactosemia: Nearly200 mutations in the GALT gene have been found andpresentation is often severe in the first few weeks of life as infants areexposed to breast/formula milk.64 Accumulation ofgalactitol in the lens causes a characteristic ‘oil droplet’ cataract.Anterior and posterior subcapsular cataract may also occur.65 Earlyrecognition and initiation of a galactose-free diet can reverse lensclouding and prevent fatal systemic consequences.66 Galactokinasedeficiency is seen as a mild form of galactosaemia and paediatric cataractis often the major clinical feature.67
