Position: Chr14:73678632 g>t
dbSNP ID: NA
Coding/Non-Coding: Coding
Mutation Type: Point, Missense
Codon Change: GGT to TGT
Reference Isoform: PSEN1 isoform 1 (467 aa)

Findings

This variant was found in one individual in a study that screened the APP, PSEN1, and PSEN2 genes in 1,431 Alzheimer’s disease (AD) patients from the Belgian neurology consortium BELNEU (Perrone et al., 2020). The authors used a targeted re-sequencing gene-panel and selected non-synonymous variants with a less than one percent minor allele frequency.

The proband’s APOE genotype was APOE3/4. The variant is absent from both the gnomAD and ExAC variant databases.
