For the roughly one in 3,000 people living with neurofibromatosis type 1, chronic pain has long been a shadow without a clear source — present even where tumors are not, defying the explanations medicine had to offer. Researchers at Cincinnati Children's have now traced that shadow to its origin: Schwann cells, the nervous system's own support structures, malfunctioning in ways that flood pain-sensing fibers with an amplifying protein called GDNF. The discovery, published in May 2026, not only reframes how NF1 pain is understood but points toward a drug already in use that may quiet those sign

Economic Lens
📈
Cincinnati researchers identified GDNF protein from abnormal Schwann cells as a chronic pain driver in neurofibromatosis type 1, with MEK inhibitor mirdametinib showing therapeutic promise, potentially expanding treatment options for rare genetic disorder.

NF1 patients (1 in 3,000 people) could gain access to new pain management therapies, potentially improving quality of life and reducing reliance on opioids or other pain medications; expanded use of existing MEK inhibitor (mirdametinib) could increase treatment accessibility.
FDA may expedite review of mirdametinib for NF1-related chronic pain indication; potential expansion of orphan drug designations and accelerated approval pathways; insurance coverage discussions for rare disease treatments; possible research funding increases for neurofibromatosis studies.
