Genes affected
SLC35D2 (HGNC:20799): (solute carrier family 35 member D2) Nucleotide sugars, which are synthesized in the cytosol or the nucleus, are high-energy donor substrates for glycosyltransferases located in the lumen of the endoplasmic reticulum and Golgi apparatus. Translocation of nucleotide sugars from the cytosol into the lumen compartment is mediated by specific nucleotide sugar transporters, such as SLC35D2 (Suda et al., 2004 [PubMed 15082721]).[supplied by OMIM, Mar 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.312C>A (p.N104K) alteration is located in exon 4 (coding exon 4) of the SLC35D2 gene. This alteration results from a C to A substitution at nucleotide position 312, causing the asparagine (N) at amino acid position 104 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
