Located in the PSEN1 gene, rs63750306 represents the rare variant site where all three possible single nucleotide mutations are known and considered pathogenic. The c.436A>C is also known as p.Met146Leu or M146L; the c.436A>G mutation is also known as p.Met146Val or M146V; and the c.436A>T mutation is also known as p.Met146Leu or M146L.
All three mutations are considered dominantly inherited pathogenic mutations leading to early-onset Alzheimer's disease and are listed in either ClinVar, OMIM and/or AlzForum.
23andMe calls the A>T variant: i5047522
The A>C variant is reported in [PMID 28350801
