SLC35A3

protein-coding

solute carrier family 35 member A3, the group of Solute carrier family 35

Gene summary

This gene encodes a UDP-N-acetylglucosamine transporter found in the golgi apparatus membrane. In cattle, a missense mutation in this gene causes complex vertebral malformation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_012243.3. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Function
FUNCTION: Uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) transporter in the Golgi apparatus. May supply UDP-GlcNAc as substrate for Golgi-resident glycosyltransferases that generate branching of diantennary oligosaccharides. {ECO:0000269|PubMed:10393322}.;
Disease
DISEASE: Arthrogryposis, mental retardation, and seizures (AMRS) [MIM:615553]: A disease characterized by arthrogryposis, mental retardation, autism spectrum disorder, and epilepsy. Additional features include limb malformations, distal joint involvement, microcephaly, retromicrognathia, and general muscle hypotonia. {ECO:0000269|PubMed:24031089}. Note=The disease is caused by mutations affecting the gene represented in this entry. In Golgi vesicles isolated from patient fibroblasts the transport of the respective nucleotide sugar is significantly reduced causing a massive decrease in the content of cell surface expressed highly branched N-glycans and a concomitant sharp increase of lower branched glycoforms.;
