Variant summary

Our verdict is Pathogenic. The variant received 21 ACMG points: 21P and 0B. PS3 PM1 PM2 PP2 PP3_Strong PP5_Very_Strong

The NM_000021.4(PSEN1):​c.791C>T​(p.Pro264Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,457,910 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV005201535: Published functional studies demonstrate a damaging effect on protein folding, localization, and function (Ben-Gedalya et al., 2015" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. P264P) has been classified as Likely benign.

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

Our verdict: Pathogenic. The variant received 21 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV005201535: Published functional studies demonstrate a damaging effect on protein folding, localization, and function (Ben-Gedalya et al., 2015; Sun et al., 2017); SCV001588727: Experimental studies have shown that this missense change affects PSEN1 function (PMID: 11959395, 26438723).
• PM1: In a hotspot region, there are 14 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 10 uncertain in NM_000021.4
• PM2: Very rare variant in population databases, with high coverage
• 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 early-onset autosomal dominant Alzheimer disease, Pick disease, semantic dementia, Alzheimer disease 3, familial isolated dilated cardiomyopathy, dilated cardiomyopathy, dilated cardiomyopathy 1U, acne inversa, familial, 3, behavioral variant of frontotemporal dementia.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.975
• PP5: Variant 14-73198052-C-T is Pathogenic according to our data. Variant chr14-73198052-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 98080.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
