DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for familial hypocalciuric hypercalcemia — screening already-approved drugs against its 3-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.
Disease moduleFamilial hypocalciuric hypercalcemia maps to a 3-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead
No approved-drug candidate for familial hypocalciuric hypercalcemia is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.
Molecular view
calcium sensing receptor (CASR) — CASR is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

Familial Hypocalciuric Hypercalcemia and Neonatal Severe Hyperparathyroidism
AbstractFamilial hypocalciuric hypercalcemia (FHH) and neonatal severe hyperparathyroidism (NSHPT) are genetically determined variants of primary hyperparathyroidism. FHH usually has a benign course, and patients do not require treatment, whereas NSHPT is a severe disorder often requiring early parathyroidectomy for young patients to survive. Recent discoveries in the genetic basis and new findings in therapeutic approaches have led to a great interest in these rare diseases.

A Novel Mutation in the Calcium-Sensing Receptor Gene in a Chinese Subject with Persistent Hypercalcemia and Hypocalciuria1
AbstractFamilial hypocalciuric hypercalcemia (FHH) is an autosomal dominant disorder characterized by high penetrance of relatively benign, lifelong persistent hypercalcemia and hypocalciuria. By contrast, neonatal severe hyperparathyroidism represents a life-threatening form of hypercalcemia that can cause the early newborn mortality if immediate intervention is not undertaken. Both disorders are due to inactivation mutation of the human calcium-sensing receptor (CaSR) gene on chromosome 3q21-24. Up to now, more than 30 mutations in the CaSR gene associated with FHH have been described. In this study, we analyzed one 79-yr-old male with hypocalciuric hypercalcemia without siblings or children to compare with an additional group of 50 normal Chinese subjects in Taiwan. DNA sequence analysis of the CaSR gene was performed. The result showed that the proband had a heterozygous nonsense mutation in exon 7 of the CaSR gene at codon 648 (CGA-->TGA/Arg-->Ter). This mutation, located in the COOH-terminal of the first intracellular loop of the CaSR, predicts a markedly truncated protein. We have identified a novel R648X mutation in the CaSR gene in one patient with FHH in Taiwan
