CALHM1 (calcium homeostasis modulator 1)

Gene

• Entrez ID: 255022
• Gene name: Calcium homeostasis modulator 1
• Gene symbol: CALHM1
• Synonyms: FAM26C
• Chromosome: 10
• Chromosome location: 10q24.33
• Summary: This gene encodes a calcium channel that plays a role in processing of amyloid-beta precursor protein. A polymorphism at this locus has been reported to be associated with susceptibility to late-onset Alzheimer`s disease in some populations, but the patho
