About GALT

Cytogenetic location: 9p13.3 Genomic coordinates (GRCh38): 9:34,646,675-34,651,035 (from NCBI)

This gene has 29 transcripts (splice variants), 168 orthologues and is associated with 3 phenotypes. Ubiquitous expression in duodenum (RPKM 23.8), liver (RPKM 21.4) and 25 other tissues.

Summary

Galactose-1-phosphate uridyl transferase (GALT) catalyzes the second step of the Leloir pathway of galactose metabolism, namely the conversion of UDP-glucose + galactose-1-phosphate to glucose-1-phosphate + UDP-galactose. The absence of this Enzyme results in classic galactosemia in humans and can be fatal in the newborn period if lactose is not removed from the diet. The pathophysiology of galactosemia has not been clearly defined. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
