Genes affected

PMS1 (HGNC:9121): (PMS1 homolog 1, mismatch repair system component) This gene encodes a protein belonging to the DNA mismatch repair mutL/hexB family. This protein is thought to be involved in the repair of DNA mismatches, and it can form heterodimers with MLH1, a known DNA mismatch repair protein. Mutations in this gene cause hereditary nonpolyposis colorectal cancer type 3 (HNPCC3) either alone or in combination with mutations in other genes involved in the HNPCC phenotype, which is also known as Lynch syndrome.

Likely benign, criteria provided, single submitter	not provided	Breakthrough Genomics, Breakthrough Genomics	-	- -
Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The PMS1 p.Glu361Lys variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs151325573) and ClinVar (classified as a VUS by Illumina and Genomic Research Center, Shahid Beheshti University of Medical Sciences for Lynch Syndrome). The variant was identified in control databases in 596 of 280400 chromosomes (3 homozygous) at a frequency of 0.002126 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 101 of 10314 chromosomes (freq: 0.009793), Latino in 103 of 35214 chromosomes (freq: 0.002925), European (non-Finnish) in 354 of 128070 chromosomes (freq: 0.002764), Other in 18 of 7128 chromosomes (freq: 0.002525), African in 13 of 24308 chromosomes (freq: 0.000535), South Asian in 6 of 30404 chromosomes (freq: 0.000197) and European (Finnish) in 1 of 25054 chromosomes (freq: 0.00004); it was not observed in the East Asian population. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Glu361 residue is not conserved in mammals and four out of five computational analyses (SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
