Genes affected

CALHM1 (HGNC:23494): (calcium homeostasis modulator 1) 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 pathogenicity of this polymorphism is unclear.[provided by RefSeq, Mar 2010]

The c.976G>A (p.G326S) alteration is located in exon 2 (coding exon 2) of the CALHM1 gene. This alteration results from a G to A substitution at nucleotide position 976, causing the glycine (G) at amino acid position 326 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
