Molecular Diagnostics

Biomarkers of Oral Cancer Discovered

Epigenetics, the non-genetic influences on gene expression, is a powerful mechanism capable of altering gene expression in cancer cells without changes to the DNA sequence, and can cause tumor progression. More...

Human Microbiome Features Stratify Children with IBS

Irritable bowel syndrome (IBS) is a disruptive gastrointestinal condition characterized by bloating, changes in bowel habits, and pain that affects up to 20% of the world's population (children and adults). Increasing evidence indicates that the onset and symptoms of IBS are related to the gut microbiome. More...

Unexplained Liver Disease Diagnosed by Whole-Exome Sequencing

A recent paper promoted the use of whole-exome sequencing (WES) to detect and diagnose cases of unexplained liver disease. More...

Multi-Gene Panel Testing Catches Cancer Risk Variants

Over 608,000 patients with ovarian, breast, pancreatic, prostate and colorectal cancer are diagnosed each year. Current guidelines recommend testing all patients with ovarian and pancreatic cancer, as well as patients with prostate, breast and colorectal cancer (CRC) who meet certain criteria. More...

High-Res Genotyping Improves Survival for Stem Cell Transplantation

Allogeneic hematopoietic cell transplantation (HCT) provides a curative treatment option for individuals with hematologic diseases. Recipients and donors are considered to be compatible or “well matched” if they share a high degree of genetic similarity at their human leukocyte antigen (HLA) loci. More...

Sequencing Finds Germline Risk Variants in Pediatric Cancer Cases

Somatic panel sequencing is increasingly used in pediatric oncology to aid in cancer diagnosis, risk classification, identification of targetable biomarkers, and treatment planning. As tumor tissues contain both somatic and germline variants, tumor profiling can uncover potential germline changes incidentally. More...

Biochip Assay Rapidly Detects Mycobacterial Isolates

Tuberculosis (TB) has bounced back in the past several decades and has become the main cause of death from one single infectious disease, mainly due to the epidemic of human immunodeficiency virus (HIV). More...
