Genes affected

ST3GAL4 (HGNC:10864): (ST3 beta-galactoside alpha-2,3-sialyltransferase 4) This gene encodes a member of the glycosyltransferase 29 family, a group of enzymes involved in protein glycosylation. The encoded protein is targeted to Golgi membranes but may be proteolytically processed and secreted. The gene product may also be involved in the increased expression of sialyl Lewis X antigen seen in inflammatory responses. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Ambry Genetics

Apr 13, 2022

The c.43C>G (p.L15V) alteration is located in exon 3 (coding exon 2) of the ST3GAL4 gene. This alteration results from a C to G substitution at nucleotide position 43, causing the leucine (L) at amino acid position 15 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
