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]

Ambry Genetics

Oct 07, 2022

The c.211T>C (p.Y71H) alteration is located in exon 3 (coding exon 2) of the B3GAT1 gene. This alteration results from a T to C substitution at nucleotide position 211, causing the tyrosine (Y) at amino acid position 71 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
