Abstract：
:The ability of EB virus-transformed lymphoblasts with undetectable galactose-1-phosphate uridyltransferase (GALT) from 15 galactosaemic patients to oxidize [1-(14)C]galactose to 14CO2 was compared to that of cells from 7 normal subjects. The oxidation of galactose but not of glucose was markedly diminished by cells from Q188R homozygous galactosaemic patients but was not absent. After 2.5 h these cells liberated 14CO2 at nearly 3% and at 5 h up to 9% of normal. Cells from patients homozygous for the S135L mutation produced much larger amounts of 14CO2 (15-17% of normal) and were distinguishable from the Q188R homozygous cells. A cell line with a homozygous deletion of the GALT gene oxidized galactose at 7% of the normal rate, suggesting that pathways(s) other than GALT exist in these cells as well as Q188R homozygous cells for oxidation of galactose to CO2. Concentration dependence studies are consistent with the presence of a pathway that is unsaturable or has a very high Km The ability of 10(7) lymphoblasts with the S135L genotype to oxidize more than 7% of the sugar to 14CO2 in 5 h suggests the presence of residual GALT despite the inability to detect the activity by enzymatic analysis.
