The GALT gene is associated with autosomal recessive classic galactosemia (MedGen UID: 344772).
Order this gene as a single gene test.
GALT: Analysis includes the 5 kb deletion NM_000155.3:c.[-1039_753del; 820+50_*789delinsGAATAGACCCCA] as well as the Duarte variant NM_000155.3: c.-119_-116delGTCA.
Invitae tests that include this gene:
Pathogenic variants in the GALT gene are the only known cause of classic galactosemia.
The GALT gene encodes galactose-1-phosphate uridylyltransferase, the second enzyme in the galactose degredation pathway, which catalyzes the conversion of galactose-1-phosphate to glucose.
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.
