On this Rare Disease Day, we share the real-world impact of iHope’s mission - a story of precision medicine without borders.
Brianda, from Mexico, showed developmental delays from early childhood such as late walking, delayed speech, and balance difficulties with frequent falls. Despite extensive testing, including normal brain imaging and muscle studies, her family was left without answers.
Through the iHope program, Brianda received exome sequencing at no cost to her family. Testing facilitated by Mendelics Laboratory in Brazil identified a pathogenic variant in the PDHA1 gene, confirming a diagnosis of pyruvate dehydrogenase complex deficiency.
With a diagnosis in hand, her care team acted. Brianda transitioned to a ketogenic diet and began vitamin B1 supplementation. Therapists and her parents soon reported noticeable and meaningful improvements.
This is why access to comprehensive genomic testing, including exome and genome sequencing, is critical.
iHope connects children with suspected genetic conditions to cutting-edge genomic testing, removing financial barriers and accelerating diagnosis. iHope has partners in 14 countries with a core mission of building a worldwide network dedicated to ending the diagnostic odyssey for rare disease families.
