Molecular Diagnostics

Image: Summary of findings in primary BRCA2mut/+ breast tissues: Epithelial progenitor cells of heterozygous germline BRCA2 carriers exhibit DNA damage, failed replication stress, and damage responses, together with attenuated apoptosis. Loss of heterozygosity (LOH) analyses suggests that these findings may reflect a haploinsufficient phenotype for BRCA2 in vivo (Photo courtesy of Massachusetts General Hospital).

Single-Cell Sequencing Identifies Breast Cancer Risk

 Women harboring heterozygous germline mutations of BRCA2 have a 50% to 80% risk of developing breast cancer, yet the pathogenesis of these cancers is poorly understood. Breast cancers arising in women who inherit heterozygous mutations in BRCA2 are associated with a high prevalence of genomic alterations and aggressive clinical behavior. More...

Novel Enrichment Technology Indicates High Performance for Multi-Cancer Detection

 Breast, lung, pancreatic, and prostate cancer make up 41% of the cancer incidence in the USA. Early detection and a deep understanding of each cancer remain critical for implementing the highest quality of care. More...

Liquid Biopsy Predicts Prognosis of Gastric Cancer Following Chemotherapy or Surgery

 A liquid biopsy approach, which utilized analyses of matched circulating DNA (cfDNA) and white blood cells from the same patient, was used to predict recurrence of gastric cancer in patients after surgery. More...

Image: The myTAIHEART test is a powerful non-invasive test that uses a small sample of blood to determine if a patient is at a low or increased risk of rejecting their heart transplant. myTAIHEART works by measuring the fraction of cell-free DNA (cfDNA) present in the bloodstream that is attributable to the transplanted heart. An elevated donor fraction (DF%) is associated with an increased risk of acute cellular rejection (Photo courtesy of TAI Diagnostics).

Heart Transplant Monitoring Test Validated

 A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure or severe coronary artery disease. Noninvasive risk assessment for rejection in heart transplant recipients, both adult and pediatric, is an imperative and urgent clinical need. More...

Real-Time PCR Developed for Eumycetoma Diagnosis

 Mycetoma, a progressive and disfiguring disease, is one of the neglected tropical diseases, caused by both bacteria and fungi. Eumycetoma is the fungal type and mainly caused by species of the genus Madurella. More...

Technique Predicts Cancer Recurrence Risk for Melanoma Patients

 Many primary melanomas can be cured by having this lesion removed, but melanoma can also recur and spread; an analysis of the removed lesion can offer some information on the likelihood that the cancer will recur. More...
