Patients exhibit short stature, dysmorphic bones, and severe growth plate abnormalities, as well as hypercalcemia, hypercalciuria, hypophosphatemia, and reduced plasma PTH levels. Humanized PTH1R (hPTH1R) mice expressing the H223R-hPTH1R JMC mutation die early without breeding. We therefore generated and characterized a stable mouse line expressing the T410R-hPTH1R allele, which confers a milder disease phenotype in patients. Mutant mice show near-normal longevity and reproductive capacity yet exhibit a profound skeletal phenotype characteristic of the disease. The long bones of T410R mice are markedly misshapen and have expanded metaphyses with disarrayed chondrocyte zones in growth plates and reduced primary spongiosa. PET\/CT scanning revealed diminished uptake of [\n                    <jats:sup>18<\/jats:sup>\n                    F]-sodium fluoride in the growth plate area, consistent with reduced mineralization and vascularization. Genetic ablation of\n                    <jats:italic toggle=\"yes\">Hdac4<\/jats:italic>\n                    rescued the growth plate abnormalities in T410R mice, thereby establishing the PTH1R-G\u03b1s-cAMP-PKA-SIK3-HDAC4\/5 pathway as the main mediator of growth plate abnormalities in JMC. Serum calcium was elevated and endogenous PTH was suppressed in T410R mice, and both parameters could be normalized by acute injection of an optimized PTH inverse agonist peptide. The T410R mouse thus represents a stable animal model of JMC that recapitulates the abnormalities in skeletal development and mineral ion homeostasis which characterize this disease. The mice should help efforts to further define the cellular and molecular mechanisms underlying the JMC phenotype and to develop a potential mode of therapy.\n
