A form of galactosemia, an inborn error of galactose metabolism typically manifesting in the neonatal period, after ingestion of galactose, with jaundice, hepatosplenomegaly, hepatocellular insufficiency, food intolerance, hypoglycemia, renal tubular dysfunction, muscle hypotonia, sepsis and cataract. GALAC3 is an autosomal recessive form caused by galactose epimerase deficiency. It can manifest as benign, peripheral form with mild symptoms and enzymatic deficiency in circulating blood cells only. A second form, known as generalized epimerase deficiency, is characterized by undetectable levels of enzyme activity in all tissues and severe clinical features, including restricted growth and intellectual disability.
