Genes affected

FUT9 (HGNC:4020): (fucosyltransferase 9) The protein encoded by this gene belongs to the glycosyltransferase family. It is localized to the golgi, and catalyzes the last step in the biosynthesis of Lewis X (LeX) antigen, the addition of a fucose to precursor polysaccharides. This protein is one of the few fucosyltransferases that synthesizes the LeX oligosaccharide (CD15) expressed in the organ buds progressing in mesenchyma during embryogenesis. It is also responsible for the expression of CD15 in mature granulocytes. A common haplotype of this gene has also been associated with susceptibility to placental malaria infection.

Collection Method:clinical testing

The c.983G>A (p.R328Q) alteration is located in exon 3 (coding exon 1) of the FUT9 gene. This alteration results from a G to A substitution at nucleotide position 983, causing the arginine (R) at amino acid position 328 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
