Genes affected

SLC35B4 (HGNC:20584): (solute carrier family 35 member B4) Glycosyltransferases, such as SLC35B4, transport nucleotide sugars from the cytoplasm where they are synthesized, to the Golgi apparatus where they are utilized in the synthesis of glycoproteins, glycolipids, and proteoglycans (Ashikov et al., 2005 [PubMed 15911612]).[supplied by OMIM, Mar 2008]

The c.691G>A (p.V231I) alteration is located in exon 9 (coding exon 9) of the SLC35B4 gene. This alteration results from a G to A substitution at nucleotide position 691, causing the valine (V) at amino acid position 231 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
