Associated Genetic Biomarkers
Werner syndrome, RecQ helicase-like (WRN) is a gene that encodes a protein that functions as a DNA helicase. Missense mutations, silent mutations, nonsense mutations, in-frame deletions, and frameshift deletions are observed in cancers such as peritoneal cancer, colon cancer, and stomach cancer.
WRN is altered in 3.21% of all cancers with lung adenocarcinoma, colon adenocarcinoma, endometrial endometrioid adenocarcinoma, melanoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations .
The most common alterations in WRN are WRN Mutation (2.86%), WRN Loss (0.30%), WRN S1128fs (0.09%), WRN T172P (0.06%), and WRN Amplification (0.04%) .
WRN status serves as an inclusion eligibility criteria in 4 clinical trials, of which 3 are open and 1 is closed. Of the trials that contain WRN status as an inclusion criterion, 1 is phase 1 (1 open) and 3 are phase 2 (2 open).
Trials with WRN status in the inclusion eligibility criteria most commonly target breast carcinoma, malignant solid tumor, small cell lung carcinoma, and urothelial carcinoma .
The most frequent alterations to serve as inclusion eligibility criteria are WRN Loss, WRN Mutation, and WRN Mutation (germline) .
Niraparib, olaparib, carboplatin, cisplatin, and gemcitabine are the most frequent therapies in trials with WRN as an inclusion criteria .

WRN is altered in 1.54% of small cell lung carcinoma patients .
WRN is an inclusion criterion in 1 clinical trial for small cell lung carcinoma, of which 0 are open and 1 is closed. Of the trial that contains WRN status and small cell lung carcinoma as inclusion criteria, 1 is phase 2 (0 open) .
