The recorded framework is ClinGen PMS2 VCEP v2.0.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
The HCI MAPP/PP2 Prior P score for p.Gly29Ala (PMS2_00179) is 0.8883, which exceeds the VCEP PP3_Moderate threshold of >0.81. This in silico prior probability supports a pathogenic computational prediction.
Per VCEP PMS2 rule, BS1_Strong applies when gnomAD v4 grpmax filtering allele frequency is ≥ 0.00028 (0.028%) and < 0.0028 (0.28%), and the variant is excluded as a founder pathogenic variant. The grpmax FAF for this variant is 0.00037135 (0.037%), which falls within this range. The variant is observed across multiple populations with highest frequency in Ashkenazi Jewish (0.699%), but there is no definitive evidence of founder pathogenic status. One homozygote is observed in gnomAD v4, further supporting that this variant is unlikely to be highly penetrant.

NM_000535.7:c.86G>C (p.Gly29Ala) is a missense variant in exon 2 of PMS2, a gene in which loss-of-function is an established mechanism for Lynch syndrome.
This variant is present in gnomAD v4.1 at an allele frequency of 0.050% (808/1,610,736 alleles, grpmax FAF=0.037%), which meets the VCEP PMS2 BS1_Strong threshold (grpmax FAF ≥ 0.028% and < 0.28%). One homozygote is observed in both gnomAD v2 and v4, further supporting that this variant is unlikely to be highly penetrant.
The HCI MAPP/PP2 Prior P score of 0.8883 exceeds the VCEP PP3_Moderate threshold (>0.81), providing in silico evidence for a deleterious effect.
This variant is reported in ClinVar as Likely benign by 10 clinical laboratories and as Benign by 2 laboratories, though 5 laboratories classify it as Uncertain significance. The overall ClinVar classification is Likely benign with review status of criteria provided, single submitter.
SpliceAI predicts no splicing impact (max delta score 0.00), and the variant does not lie in a statistically significant mutational hotspot.
No functional studies, segregation data, tumor phenotype data, or de novo observations are available for this variant. No peer-reviewed publication specifically mentions NM_000535.7:c.86G>C.
