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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.638C>T (p.A213V) alteration is located in exon 2 (coding exon 2) of the CALHM1 gene. This alteration results from a C to T substitution at nucleotide position 638, causing the alanine (A) at amino acid position 213 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
