Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 4P and 5B. PM1PP3_ModerateBS1_SupportingBS2

The NM_000447.3(PSEN2):​c.710C>T​(p.Ala237Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000229 in 1,614,026 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. A237A) has been classified as Likely benign.

Genes affected
PSEN2 (HGNC:9509): (presenilin 2) Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1 or PSEN2) or 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 act are protease enzymes. Two alternatively spliced transcript variants encoding different isoforms of PSEN2 have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1
In a transmembrane_region Helical (size 20) in uniprot entity PSN2_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_000447.3
PP3
MetaRNN computational evidence supports a deleterious effect, 0.871
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000239 (35/1461886) while in subpopulation EAS AF= 0.000151 (6/39700). AF 95% confidence interval is 0.0000651. There are 0 homozygotes in gnomad4_exome. There are 16 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 35 AD gene.
