Genes affected

PSEN1 (HGNC:9508): (presenilin 1) Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1; PSEN2) or in the amyloid precursor protein (APP). These disease-linked mutations result in increased production of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought that the presenilins are involved in the cleavage of the Notch receptor, such that they either directly regulate gamma-secretase activity or themselves are protease enzymes. Several alternatively spliced transcript variants encoding different isoforms have been identified for this gene, the full-length nature of only some have been determined.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM1

In a topological_domain Lumenal (size 28) in uniprot entity PSN1_HUMAN there are 21 pathogenic changes around while only 0 benign (100%) in NM_000021.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PSEN1. . Gene score misZ 2.1558 (greater than the threshold 3.09). Trascript score misZ 3.0986 (greater than threshold 3.09). GenCC has associacion of gene with acne inversa, familial, 3, dilated cardiomyopathy, Alzheimer disease 3, early-onset autosomal dominant Alzheimer disease, semantic dementia, Pick disease, familial isolated dilated cardiomyopathy, dilated cardiomyopathy 1U, behavioral variant of frontotemporal dementia.

BS2

High AC in GnomAdExome4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
