Congenital Disorders of Glycosylation Gene Panel, Varies
Use
This test is useful for establishing a molecular diagnosis for patients with congenital disorders of glycosylation. It is also helpful for identifying variants within genes associated with congenital disorders of glycosylation, which allows for predictive testing of at-risk family members.
Special Instructions
A previous bone marrow transplant from an allogenic donor will interfere with testing.
Limitations
Technical limitations include regions of genes that cannot be evaluated effectively due to homology, high GC content, and repetitive sequences. Next-generation sequencing may not detect all genomic variants, and false-negative or false-positive results may occur. Deletions-insertions of 40 or more bp may be less reliably detected.
