The coding exons and flanking consensus splice sites of the GALC gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.
Analysis for the presence of GALC (OMIM:606890) variants in patients with Krabbe disease.
Interpretive report provided.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
This analysis will not identify variants in the regulatory elements or deep intronic regions of the GALC gene, and cannot detect variants in other genes associated with the clinical diagnosis. This sequencing assay may not detect large deletions, duplications or rearrangements involving GALC.
