As of 2026-09-14

Tryptophan 5-hydroxylase 1 shows clinical signal disease relevance led by pulmonary arterial hypertension. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P17752. Start with pulmonary arterial hypertension, then reuse UniProt P17752 as the stable protein anchor across project notes and exports.

pulmonary arterial hypertension

Tryptophan 5-hydroxylase 1 shows clinical signal disease relevance led by pulmonary arterial hypertension. 1 linked drug remains visible in the same block.

Start review with pulmonary arterial hypertension because it currently carries clinical signal support. Linked drugs include RODATRISTAT ETHYL. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
