There are more than 7,000 known rare diseases - conditions that each affect fewer than 1 in 2,000 people. Individually rare, collectively these conditions affect over 300 million people worldwide, many of them children. Parents of children with rare diagnoses frequently face long diagnostic odysseys, limited treatment options, and a scarcity of peer-reviewed literature. SpecialCircle Research tracks emerging science for rare neurological, genetic, and metabolic conditions including gene therapies, natural history studies, and FDA Orphan Drug designations. We explain findings from PubMed, NIH GARD, NORD, and ClinicalTrials.gov in plain language - so families navigating rare diagnoses can stay informed and empowered.
