Lifetime reanalysis until diagnosis

Nearly 300 rare genetic diseases are discovered on average each year. Continuous reanalysis increases the chances of diagnosis for undiagnosed patients.

More than 20% of undiagnosed patients can receive diagnoses by reanalyzing the initial genetic test data with newly discovered gene-disease findings (Fung JLF et al., 2020).
