Lifetime reanalysis until diagnosed

In a year, about 260 to 280 new rare genetic diseases are discovered.

Patients who have not been diagnosed last month are likely to be diagnosed this month with the newly discovered diseases.

About 15 to 30% of undiagnosed patients are diagnosed by re-analyzing the same genomic data generated by the initial genetic test. They are usually diagnosed with a newly discovered rare genetic disease (Liu P et al., 2019).
