Inherited Spastic Paraplegia Gene Panel, Varies
Use
This test is useful for establishing a molecular diagnosis for patients with hereditary spastic paraplegia. It identifies variants within 128 genes known to be associated with hereditary spastic paraplegia, allowing for predictive testing of at-risk family members. Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, recurrence risk assessment, familial screening, and genetic counseling for hereditary spastic paraplegia.

Limitations
Next-generation sequencing may not detect all types of genomic variants and has technical limitations in regions of homology, high GC content, and repetitive sequences. In some cases, false-negative or false-positive results may occur. Deletion and duplication analysis may not achieve single exon resolution due to isolated reduction in sequence coverage or inherent genomic complexity. Deletions-insertions of 40 or more bp, including mobile element insertions, may be less reliably detected than smaller delins. Results may be affected by recent blood transfusions or bone marrow transplants due to the presence of donor DNA.
