Summary of "Novel mutations associated with inherited human calcium-sensing receptor disorders: a clinical genetic study."

Molecular diagnosis is a useful diagnostic tool in calcium metabolism disorders. The calcium-sensing receptor (CaSR) is known to play a central role in the regulation of extracellular calcium homeostasis. We performed clinical, biochemical and genetic characterization of sequence anomalies in this receptor in a cohort of 130 individuals from 82 families with suspected alterations in the CASR gene, one of the largest series described.

Calcium-sensing receptor residues with loss- and gain-of-function mutations are located in regions of conformational change and cause signalling bias.

The calcium-sensing receptor (CaSR) is a homodimeric G-protein coupled receptor that signals via intracellular calcium (Ca2+i) mobilisation and phosphorylation of extracellular signal-regulated kinase...

The location of exon 4 mutations in RP1 raises challenges for genetic counselling and gene therapy.

Mutations in the photoreceptor gene RP1 lead to recessive or dominantly inherited retinitis pigmentosa (RP). Since the dominantly inherited phenotype is generally milder than recessive cases, it raise...

Inherited Forms of Primary Hyperaldosteronism: New Genes, New Phenotypes and Proposition of A New Classification.

Primary aldosteronism is a common cause of endocrine hypertension. It results from the excess production of aldosterone by the adrenal cortex and is related to increased morbidity and mortality. Most ...

The Roles of Initiating Truncal Mutations in Human Cancers: The Order of Mutations and Tumor Cell Type Matters.

We propose that initiating truncal mutations plays a special role in tumor formation by both enhancing the survival of the initiating cancer cell and by selecting for secondary mutations that contribu...

Expression and Purification of Calmodulin for NMR and Other Biophysical Applications.

Calmodulin (CaM) is a ubiquitous calcium-sensing protein that has one of the most highly conserved sequences among eukaryotes. CaM has been a useful tool for biologists studying calcium signaling for ...

Medical and Biotech [MESH] Definitions

A class of G-protein-coupled receptors that react to varying extracellular CALCIUM levels. Calcium-sensing receptors in the PARATHYROID GLANDS play an important role in the maintenance of calcium HOMEOSTASIS by regulating the release of PARATHYROID HORMONE. They differ from INTRACELLULAR CALCIUM-SENSING PROTEINS which sense intracellular calcium levels.

Intracellular signaling peptides and proteins that bind to CALCIUM. They undergo allosteric changes when bound to CALCIUM that affects their interaction with other signal-transducing molecules. They differ from CALCIUM-SENSING RECEPTORS which sense extracellular calcium levels.

A family of intracellular calcium-sensing proteins found predominately in NEURONS and PHOTORECEPTOR CELLS. They contain EF HAND MOTIFS and undergo conformational changes upon calcium-binding. Neuronal calcium-sensor proteins interact with other regulatory proteins to mediate physiological responses to a change in intracellular calcium concentration.

A naphthalene derivative and CALCIMIMETIC AGENT that increases the sensitivity of PARATHYROID GLAND calcium-sensing receptors to serum calcium. This action reduces parathyroid hormone secretion and decreases serum calcium in the treatment of PARATHYROID DISEASES.

An autosomal dominantly inherited skin disorder characterized by warty malodorous papules that coalesce into plaques. It is caused by mutations in the ATP2A2 gene encoding SERCA2 protein, one of the SARCOPLASMIC RETICULUM CALCIUM-TRANSPORTING ATPASES. The condition is similar, clinically and histologically, to BENIGN FAMILIAL PEMPHIGUS, another autosomal dominant skin disorder. Both diseases have defective calcium pumps (CALCIUM-TRANSPORTING ATPASES) and unstable desmosomal adhesion junctions (DESMOSOMES) between KERATINOCYTES.
