B3GALTL; B3GTL; B3Glc-T; Gal-T; beta3Glc-T
The B3GLCT gene is associated with autosomal recessive Peters-plus syndrome also known as B3GLCT-congenital disorder of glycosylation (Medgen UID: 163204).

Pathogenic variants in the B3GLCT gene are the only known cause of Peters plus syndrome.
The B3GLCT gene encodes a beta 3-glucosyltransferase protein. This protein transfers glucose to O-linked fucosylglycans specifically on thrombospondin Type 1 repeat (TSR) domains. Protein O-linked fucosylation is associated with many important biological functions such as Notch signaling.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
