Genes affected
B3GAT1 (HGNC:921): (beta-1,3-glucuronyltransferase 1) The protein encoded by this gene is a member of the glucuronyltransferase gene family. These enzymes exhibit strict acceptor specificity, recognizing nonreducing terminal sugars and their anomeric linkages. This gene product functions as the key enzyme in a glucuronyl transfer reaction during the biosynthesis of the carbohydrate epitope HNK-1 (human natural killer-1, also known as CD57 and LEU7). Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2021The c.287C>T (p.P96L) alteration is located in exon 3 (coding exon 2) of the B3GAT1 gene. This alteration results from a C to T substitution at nucleotide position 287, causing the proline (P) at amino acid position 96 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
