Overview
Types
Galactosemia refers to a group of autosomal recessive disorders of galactose metabolism. They are classified into the following types based on the enzymatic activity [1]
Type I/Classical
Severe deficiency or absence of the Galactose-1-phosphate uridyl transferase enzyme of the Leloir pathway in the red blood cells.[2]. This is the most severe and potentially lethal type.
Type II
Mutations in the gene encoding for the enzyme galactokinase[3]
Type III
Alterations in the gene coding for epimerase enzyme.[4] This is the mildest type.
