Abstract:
The role that the Calcium Sensing Receptor (CASR) plays in extracellular calcium regulation had been ascertained through studies of inactivating as well as activating mutations of CASR gene in a number of multiplex families. We have extended these observations to a polymorphism analysis of the intercellular domain of CASR in a cohort of healthy young women. The results demonstrate significant allelic polymorphism as a result of nonconservative changes at two specific sites. Further studies will be required to determine what, if any, relationship this may have to CASR phenotype.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Feedback Regulation of Calcium Concentration
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
