The scope of this assay is limited to repeat expansion analysis of the gene. This repeat expansion analysis may not elicit the precise number of repeats present in large expansions. Gene sequencing and deletion/duplication analysis are not included in this assay, but can be ordered separately. This analysis does not include methylation studies.
