Genes affected

FUT4 (HGNC:4015): (fucosyltransferase 4) The product of this gene transfers fucose to N-acetyllactosamine polysaccharides to generate fucosylated carbohydrate structures. It catalyzes the synthesis of the non-sialylated antigen, Lewis x (CD15). [provided by RefSeq, Jan 2009]

FUT4 links:

PIWIL4 (HGNC:18444): (piwi like RNA-mediated gene silencing 4) PIWIL4 belongs to the Argonaute family of proteins, which function in development and maintenance of germline stem cells (Sasaki et al., 2003 [PubMed 12906857]).[supplied by OMIM, Mar 2008]

The c.440G>A (p.R147Q) alteration is located in exon 1 (coding exon 1) of the FUT4 gene. This alteration results from a G to A substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
