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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 04, 2022 | The c.773T>G (p.F258C) alteration is located in exon 10 (coding exon 10) of the SLC35B4 gene. This alteration results from a T to G substitution at nucleotide position 773, causing the phenylalanine (F) at amino acid position 258 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
