Variant summary: WRN c.4216C>T (p.Arg1406X) located in the last exon results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have not been observed or classified as pathogenic by our laboratory. The variant allele was found at a frequency of 0.0031 in 250856 control chromosomes, predominantly at a frequency of 0.017 within the South Asian subpopulation in the gnomAD database, including 10 homozygotes. The observed variant frequency within South Asian control individuals in the gnomAD database is approximately 6.8 fold of the estimated maximal expected allele frequency for a pathogenic variant in WRN causing Werner Syndrome phenotype (0.0025), strongly suggesting that the variant is a benign polymorphism found primarily in populations of South Asian origin. To our knowledge, no penetrant association of c.4216C>T in individuals affected with Werner Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 with a majority consensus as benign/likely benign (n=4)(VUS, n=1). Based on the evidence outlined above, the variant was classified as benign.

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
