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]

Ambry Genetics

May 04, 2022

The c.416G>C (p.G139A) alteration is located in exon 1 (coding exon 1) of the CALHM1 gene. This alteration results from a G to C substitution at nucleotide position 416, causing the glycine (G) at amino acid position 139 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
