Target population:
Help
The target population for this test is patients suspected of having a diagnosis of a neuromuscular disorder. Please note, this assay includes analysis for the recurrent c.930+189C>T deep intronic variant in the COL6A1 gene.
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Variants are identified and evaluated using a custom collection of bioinformatic tools and comprehensively interpreted by our team of directors and genetic counselors.
