Along with offering inexpensive and rapid genetic diagnosis, NGS has also highlighted the relevance of de novo and mosaic mutations, deciphered the wide phenotypic spectrum of genes, and identified the presence of more than one rare disease in the same patient or digenic inheritance. Furthermore, the plummeting cost of sequencing has driven the adoption of NGS specialty in disease management.

An increase in the number of available registries in this area is one of the major driving factors of the industry as it enables pool data to achieve a sufficient sample size for epidemiological and/or clinical research. They play a pivotal role in assessing the feasibility of clinical trials and thus facilitate the effective planning of clinical trials and enrolment of patients. Registries accelerate service planning as well as support public health and clinical research by delivering key insights to researchers. Furthermore, registries can be deployed for the creation and dissemination of new data findings to inform clinical best practice and care, along with enabling seamless incorporation of patient data in diagnostic procedures.

Ongoing scientific advances have created new opportunities for the development of solutions that can impact the management of the disease. Collaborations are being undertaken not only across diverse medical and scientific domains but also with various stakeholder groups, such as researchers, patients, and regulators, for rare disease product development. For instance, in June 2022, the U.S. FDA revealed its program for Rare Neurodegenerative Diseases, a 5-year strategy for extending and refining the lives of people suffering from rare diseases, by evolving the progress of effective & safe medical products and enabling patient access to innovative treatments.

In addition, strategic initiatives for new product development in rare disease diagnoses further drive the growth.
