Genetic testing support for early diagnosis of suspected rare diseases will be held again this year.

In order to help undiagnosed rare disease patients receive timely treatment through early diagnosis, the Korea Centers for Disease Control and Prevention will implement the 2025 'Visiting Rare Disease Diagnosis Project' from the 19th.

More than 80% of rare diseases are genetic diseases, and early diagnosis is important, but due to the diversity and scarcity of diseases, many patients experience 'diagnosis wanderers'.




Diagnostic wandering is when a suspected rare disease travels to several hospitals for a long time to be diagnosed, and the diagnostic wandering period is the period from the date of symptom onset to the date of diagnosis of a rare disease. Korea has an average of 7.4 years (the results of the 2024 diagnostic support project), the US 7.6 years, and Europe 5 to 30 years.

Since 2023, the Korea Centers for Disease Control and Prevention has contributed to preemptive prevention management through screening potential patients and patients by supporting genetic testing not only for patients but also their families (parents and three brothers).

As a result of supporting the diagnostic test (WGS) of 410 suspected patients with rare diseases through the rare disease diagnosis support project in 2024, 129 out of a total of 410 patients were confirmed to be positive (positive rate of 31.5%), and most of the patients confirmed to be positive were children and adolescents (80.6%) and the results of timely treatment through early diagnosis were particularly remarkable in the age group. In addition, 19.6% (21 patients) were confirmed to have taken less than one year to diagnose rare diseases, and 25.2% (27 patients) for more than 10 years, contributing not only to early diagnosis of suspected patients but also to resolving diagnostic wandering of undiagnosed patients for more than 10 years.




In particular, 101 out of 129 positive people (78.2%) will be eligible for a reduction in out-of-pocket expenses, and will even receive medical expenses for rare patients based on income (less than 140% of median income, as of 2025) and property standards.

The Korea Centers for Disease Control and Prevention will expand the number of diseases subject to diagnostic support from 1248 to 1,314, 66 in 2025, and double the size of diagnostic support from the previous year (800 people) in consideration of the actual demand for diagnosis and the increasing trend of rare diseases. By expanding the number of areas and institutions requesting diagnostic tests, medical institutions will be added from the center of existing non-metropolitan (23) medical institutions to parts of the metropolitan area, and a total of 34 medical institutions (25 non-metropolitan areas and 9 metropolitan areas) will further strengthen diagnostic accessibility.

In addition, if a rare genetic disease is identified, additional family tests (a total of three parents and brothers) will be provided to manage high-risk groups such as those shown, and screening and confirmation tests will be provided for patients suspected of spinal muscular atrophy (SMA), which has a relatively high demand for treatment costs and requires early diagnosis. If the diagnosis is confirmed as a rare disease, it will be linked to state-funded policies such as the National Health Insurance Corporation calculation special system and the Korea Centers for Disease Control and Prevention's medical expenses support project for rare patients, reducing the burden of medical expenses for patients and their families, and linking timely treatment through early diagnosis.
