Invitae Metachromatic Leukodystrophy Panel
Use
The Invitae Metachromatic Leukodystrophy Panel analyzes genes associated with metachromatic leukodystrophy, a neurodegenerative lipid storage disorder causing progressive demyelination. This test aids in identifying pathogenic variants in the ARSA, PSAP, and SUMF1 genes, which are implicated in different forms of the disorder, and is indicated for individuals suspected of MLD due to clinical, neurologic, radiologic, or biochemical findings.
Special Instructions
Not provided.
Limitations
The test may not detect certain structural rearrangements, variants in complex regions, or provide full resolution of mosaicism, phasing, or mapping ambiguity. Sequence changes in promoter, non-coding regions, and certain non-coding exons may not be analyzed. Single-exon copy number events might not be detected due to sequence properties or data quality.
