Genes affected

GAL3ST1 (HGNC:24240): (galactose-3-O-sulfotransferase 1) Sulfonation, an important step in the metabolism of many drugs, xenobiotics, hormones, and neurotransmitters, is catalyzed by sulfotransferases. This gene encodes galactosylceramide sulfotransferase, which catalyzes the sulfation of membrane glycolipids including the final step in the synthesis of sulfatide, a major lipid component of the myelin sheath. This gene exhibits elevated expression in ovarian epithelial carcinoma and the encoded enzyme exhibits elevated activity in renal cell carcinoma. Mutations in this gene may be associated with reduced insulin resistance. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.893C>A (p.T298N) alteration is located in exon 4 (coding exon 2) of the GAL3ST1 gene. This alteration results from a C to A substitution at nucleotide position 893, causing the threonine (T) at amino acid position 298 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
