RecruitingClinical trialWhole Exome Sequencing in Finding Causative Variants in Germline DNA Samples From Patients With Peripheral Neuropathy Receiving Paclitaxel for Breast CancerThis research trial studies whole exome sequencing in finding causative variants in germline deoxyribonucleic acid (DNA) samples from patients with peripheral neuropathy receiving chemotherapy for breast cancer. Studying samples of germline DNA in the laboratory from patients with peripheral neuropathy receiving paclitaxel for breast cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to peripheral neuropathy.
