How EpiSign™ Works

EpiSign™ leverages cost-effective microarray technology for assessment of genome-wide DNA methylation patterns using the EpiSign™ proprietary software to enable a diagnosis for patients with rare diseases beyond the capabilities of standard genomic testing.

Utilizing peripheral blood, patients’ methylation data is screened to determine if they possess a similar methylation profile, or episignature, to a defined episignature associated with a specific rare disorder within the EpiSign™ Knowledge Database. Episignatures provide highly sensitive and specific molecular biomarkers.

What is an episignature?

An episignature is a unique and reproducible DNA methylation profile, or biomarker, associated with a specific rare disorder including genetic and environmental exposure conditions.

EpiSign™ Knowledge Database

The world’s largest epigenetic database for rare diseases containing thousands of reference samples, including a growing list of genetic conditions.

When EpiSign™ is Used

Screening patients with complex or ambiguous presentations.

Reclassification of variants of uncertain significance (VUS).

Detecting exposure to teratogens during pregnancy.

Investigating reduced penetrance or expressivity of a genetic variant.

Assessing for imprinting defects or gene silencing due to promoter hypermethylation.

Confirm clinical diagnosis when genetic variant is unknown or undetected.

EpiSign™ in Action

The EpiSign™ Clinical Testing Network emphasizes the test’s value as an adjunct to traditional DNA sequence analysis, particularly in rare diseases, showcasing a remarkable 18.7% and 32.4% diagnostic yield in comprehensive and targeted tests, respectively.
