Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 1P and 7B. PP2BP4_ModerateBP6BS2

The NM_000021.4(PSEN1):c.104G>A(p.Arg35Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00038 in 1,614,082 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R35W) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP2

Missense variant in the PSEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 113 curated pathogenic missense variants (we use a threshold of 10). The gene has 14 curated benign missense variants. Gene score misZ: 2.1558 (below the threshold of 3.09). Trascript score misZ: 3.0986 (above the threshold of 3.09). GenCC associations: The gene is linked to Alzheimer disease 3, familial isolated dilated cardiomyopathy, dilated cardiomyopathy 1U, acne inversa, familial, 3, Pick disease, behavioral variant of frontotemporal dementia, semantic dementia, early-onset autosomal dominant Alzheimer disease, dilated cardiomyopathy.

BP4

Computational evidence support a benign effect (MetaRNN=0.12319812).

BP6

Variant 14-73170813-G-A is Benign according to our data. Variant chr14-73170813-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 98004.

BS2

High AC in GnomAd4 at 44 AD gene.
