Hypocalciuric hypercalcemia, familial 1

A form of hypocalciuric hypercalcemia, a disorder of mineral homeostasis that is transmitted as an autosomal dominant trait with a high degree of penetrance. It is characterized biochemically by lifelong elevation of serum calcium concentrations and is associated with inappropriately low urinary calcium excretion and a normal or mildly elevated circulating parathyroid hormone level. Hypermagnesemia is typically present. Affected individuals are usually asymptomatic and the disorder is considered benign. However, chondrocalcinosis and pancreatitis occur in some adults.

A novel homozygous inactivating mutation of the calcium-sensing receptor causing familial hypocalciuric hypercalcemia complicated with primary hyperparathyroidism due to parathyroid adenoma: A case report.

The Journal of international medical research2026 Mar

Familial hypocalciuric hypercalcemia is an autosomal dominant genetic disorder characterized by mild to moderate hypercalcemia, mild hypermagnesemia, and normal or inappropriately elevated parathyroid hormone levels. Familial hypocalciuric hypercalcemia 1 is the most prevalent form of familial hypocalciuric hypercalcemia and is typically caused by heterozygous loss-of-function mutations in the calcium-sensing receptor (CaSR) gene. Homozygous CaSR mutations are more commonly associated with neonatal severe primary hyperparathyroidism. We report the case of a female patient in her early 40s harboring a novel homozygous frameshift mutation in the CaSR gene (c.2603_2604insTT), resulting in familial hypocalciuric hypercalcemia 1. The patient presented with persistent hypocalciuria, hypercalcemia, and primary hyperparathyroidism, along with a family history of consanguinity. This case highlights the phenotypic variability associated with CaSR mutations and broadens the clinical spectrum of homozygous CaSR-related disorders. Increased clinical awareness of atypical genetic presentations is essential to avoid misdiagnosis and to ensure appropriate management of patients with familial disorders of calcium homeostasis.

A novel missense variant in the calcium-sensing receptor gene in a dog with hypercalcemia.

Journal of veterinary internal medicine2026 Jan 21

A 5-year-old female spayed Border Collie cross was evaluated for a 3-year history of hypercalcemia. Abnormalities were not detected on physical examination. Parathyroid hormone (PTH) concentration was at the upper end of the reference interval, but diagnostic imaging did not identify any enlarged or ectopic parathyroid tissue. Hypercalcemia failed to resolve with unilateral parathyroidectomy, or administration of bisphosphonates, and calcimimetics. Despite hypercalcemia, urine calcium excretion was inappropriately low, consistent with Familial Hypocalciuric Hypercalcemia described in humans with calcium sensing receptor gene (CASR) mutations. Exonic sequencing of CASR of this dog revealed homozygosity for a missense variant (Glu649Lys, NP_001074978.1) with predicted pathogenicity. The variant was not present in whole genome sequencing variant calls from 2,782 dogs, including 43 Border Collies. This report identifies a CASR variant as the likely cause of hypercalcemia in this dog. Clinical suspicion for a CASR variant should occur when younger dogs present for persistent hypercalcemia, inappropriate normocalciuria, and elevated PTH concentration.

Cinacalcet therapy in symptomatic 11-year-old girl with familial hypocalciuric hypercalcemia type 3.

Pediatric nephrology (Berlin, Germany)2026 Jan 07

Familial hypocalciuric hypercalcemia (FHH) is a rare genetic disorder of calcium regulation. FHH type 3 (FHH3), caused by pathogenic variants in AP2S1, may present with clinically significant complications. Data on the treatment of this rare disorder is limited. CASE DESCRIPTION: We report an 11-year-old girl with a de novo heterozygous pathogenic variant in AP2S1 (NM_004069.6): c.44G>T p.(Arg15Leu). At the age of seven, our patient presented with hypercalcemia, hypocalciuria, and elevated parathyroid hormone (PTH), which were accompanied by low bone mineral density and persistent neurodevelopmental difficulties. Primary hyperparathyroidism and causative variants in the CASR gene were excluded, and cinacalcet was initiated. After a dose titration and vitamin D3 dose adjustments, a normalization of serum calcium and PTH was achieved, and symptoms improved substantially, although lumbar bone mineral density declined further, and neurological symptoms remained. CONCLUSIONS: This case demonstrates cinacalcet as an effective and well-tolerated therapy in FHH3, with unresolved questions regarding skeletal and neurocognitive outcomes.

Praxis2025 Dec

Background: Distinguishing familial hypocalciuric hypercalcemia (FHH) a rare cause of usually mild, parathyroid hormone-dependent hypercalcemia from other causes is central for management due to its benign and usually mild course. Case: Diagnostic approach to a mild hypercalcemia in a 36-years-old female with FHH. Conclusion: This case highlights the importance of a precise and stepwise diagnostic approach to identify rare causes of hypercalcemia like FHH, an autosomal-dominant inherited, pathogenic variant of the calcium sensing receptor. Diagnostik und Management einer seltenen ­Hyperkalzämie – Ursache. Hintergrund: Die Abgrenzung der familiären hypokalziurischen Hyperkalzämie (FHH), einer seltenen Ursache einer meist milden, PTH-abhängigen Hyperkalzämie, ist hinsichtlich des Managements essenziell aufgrund des benignen Verlaufs. Fall: Präsentation des diagnostischen Vorgehens zur Abklärung einer milden Hyperkalzämie bei einer 36-jährigen Patientin mit molekulargenetisch bestätigter familiärer, hypokalziurischer Hyperkalzämie. Schlussfolgerung: Verdeutlicht wird die Wichtigkeit einer exakten Anamnese und stufenweisen Dia­gnostik, um seltene Ursachen einer Hyperkalzämie wie die FHH zu erkennen und unnötige Abklärungen, Behandlungen und Verlaufskontrollen zu verhindern. Schlüsselwörter: Hyperkalzämie, familiäre hypokalziurische Hyperkalzämie, primärer Hyperparathyreoidismus, Parathyreoidektomie, ­Parathormon.
