lysoSEEK® Sequence Analysis for Lysosomal Storage Disorders


Next Generation Sequencing test focused on early identification of genes associated with potentially treatable storage disorders

Lysosomal storage disorders are part of the differential diagnosis of several, diverse perinatal and childhood phenotypes, which are extremely variable in both onset and clinical severity. Prompt diagnosis (within the first year), including genetic testing, may enable early treatment (e.g. enzyme replacement therapy), possibly preventing irreversible clinical consequences.

Courtagen’s lysoSEEK® panel provides extensive genetic analysis and clinical interpretation of data generated by the complete sequencing of 94 genes associated with close to 60 metabolic disorders.  The test seeks out enzymatic deficiencies in the lysosomes, and looks at additional genes useful for differential diagnoses.
