Insights
Japan
Area of Science:
- Medical genetics
- Public health policy
- Rare disease research
Background:
- Japan has achieved universal healthcare since 1961, resulting in high life expectancy and low infant mortality.
- The National Program on Rare and Intractable Diseases, established in 1972, supports patients and promotes research.
- Over half of the diseases in the program are Mendelian disorders, driving genetic research.
Purpose of the Study:
- To highlight Japan's advancements in rare and intractable disease management.
- To showcase the impact of national programs on medical genetics research.
- To introduce recent genomic medicine initiatives in Japan.
Main Methods:
- Analysis of Japan's universal healthcare system's health outcomes.
- Review of the National Program on Rare and Intractable Diseases' scope and impact.
- Overview of government-supported genomic medicine initiatives.
Main Results:
- Universal healthcare contributes to excellent public health indicators.
- The National Program has significantly advanced rare disease research, identifying numerous causative genes.
- Government support has spurred genomic medicine initiatives, including undiagnosed disease programs and variant databases.
Conclusions:
- Japan's integrated approach to healthcare and rare disease research has yielded significant public health benefits.
- Continued government investment in genomic medicine promises further advancements in diagnosing and treating rare genetic disorders.
- The success of national programs underscores the importance of policy in driving scientific discovery and patient support.
Abstract:
Since 1961, all Japanese citizens have belonged to one of the available medical care insurance systems. This "universal care" system has contributed to the maintenance of health: the life expectancy at birth was 84 years in 2016, and the infant mortality rate (the number of infants dying before reaching 1 year of age) was 2.0 per 1,000 live births, which is one of the lowest rates in the world. The Japanese government initiated the National Program on Rare and Intractable Diseases in 1972. This program has promoted research and expanded support for patients with rare and intractable diseases. Registered patients are eligible for a subsidy scheme that helps to cover medical care costs. Among the 331 diseases that are currently included in this program, more than half of the diseases are Mendelian disorders. The National Program on Rare and Intractable Diseases has fostered research in medical genetics in Japan and many causative genes for Mendelian diseases have been identified by Japanese geneticists. Recently, the Japanese government has determined to support several genomic medicine initiatives including the undiagnosed disease program (Initiative on Rare and Undiagnosed Diseases) and pathogenic variant databases.
