Variant summary
Our verdict is Benign. Variant got -17 ACMG points: 0P and 17B. BP4BP6_Very_StrongBS1BS2
The NM_000447.3(PSEN2):c.389C>T(p.Ser130Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0012 in 1,614,032 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. S130S) has been classified as Likely benign.

Alzheimer disease 4 Pathogenic:1Benign:2
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -

Variant summary: PSEN2 c.389C>T (p.Ser130Leu) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0012 in 1607058 control chromosomes, predominantly at a frequency of 0.0015 within the Non-Finnish European subpopulation in the gnomAD database (v4.1 dataset), including 3 homozygotes. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database exceeds the estimated maximal expected allele frequency for a pathogenic variant in PSEN2 causing Alzheimer Disease 4 phenotype. c.389C>T has been reported in the literature in individuals affected with Alzheimer Disease (e.g. Tedde_2003). However, at least one publication reports experimental evidence evaluating an impact on protein function, and demonstrated that the variant didn't alter amyloid beta (Abeta) peptide generation from beta-amyloid precursor protein (APP), suggesting that the variant represent a polymorphisms rather than disease-causing mutation (Walker_2005). In addition, the variant was also reported in individuals affected with idiopathic dilated cardiomyopathy (Li_2006), however current evidence is not sufficient to support the association of PSEN2 with this phenotype. The following publications have been ascertained in the context of this evaluation (PMID: 14623725, 15663477, 7186461, 20375137). ClinVar contains an entry for this variant (Variation ID: 8852). Based on the evidence outlined above, the variant was classified as likely benign. -
