Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP6BS1

The NM_000535.7(PMS2):c.1037A>G(p.Gln346Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000285 in 1,611,994 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. Q346P) has been classified as Uncertain significance.

Genes affected

PMS2 (HGNC:9122): (PMS1 homolog 2, mismatch repair system component) The protein encoded by this gene is a key component of the mismatch repair system that functions to correct DNA mismatches and small insertions and deletions that can occur during DNA replication and homologous recombination. This protein forms heterodimers with the gene product of the mutL homolog 1 (MLH1) gene to form the MutL-alpha heterodimer. The MutL-alpha heterodimer possesses an endonucleolytic activity that is activated following recognition of mismatches and insertion/deletion loops by the MutS-alpha and MutS-beta heterodimers, and is necessary for removal of the mismatched DNA. There is a DQHA(X)2E(X)4E motif found at the C-terminus of the protein encoded by this gene that forms part of the active site of the nuclease. Mutations in this gene have been associated with hereditary nonpolyposis colorectal cancer (HNPCC; also known as Lynch syndrome) and Turcot syndrome. [provided by RefSeq, Apr 2016]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP6

Variant 7-5989907-T-C is Benign according to our data. Variant chr7-5989907-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 455635.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000301 (44/1459812) while in subpopulation SAS AF = 0.000477 (41/86020). AF 95% confidence interval is 0.00036. There are 0 homozygotes in GnomAdExome4. There are 34 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.
