Sequencing Assay Adopted for Advanced Lung Cancer Reflex Testing

Guidelines are rapidly moving toward upfront profiling with next-generation sequencing (NGS) of all advanced lung cancers, but there are still practical issues with this testing method that can limit clinical testing and prevent or delay patients being started on targeted therapies. More...

Neuroblastoma Molecular Analysis Leads to Prognostic Markers

Neuroblastoma is a pediatric tumor of the sympathetic nervous system. Its clinical course ranges from spontaneous tumor regression to fatal progression. It most frequently starts from one of the adrenal glands, but can also develop in the neck, chest, abdomen, or spine. More...

Genetic and Epigenetic Features Found in Glioma Tumors

Neurofibromatosis type 1 (NF1) is a multisystem genetic disorder that is characterized by cutaneous findings, most notably café-au-lait spots and axillary freckling, by skeletal dysplasias, and by the growth of both benign and malignant nervous system tumors, most notably benign neurofibromas. More...

Tick-Borne Diseases Diagnosed with Multiplex Molecular Panel

Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. Tick-borne illnesses are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. More...

HCV-RNA Present in Body Fluids in High Viral Load Patients

Hepatitis C virus (HCV) causes both acute and chronic infection. Acute HCV infection is usually asymptomatic, and is only very rarely (if ever) associated with life-threatening disease. About 15%–45% of infected persons spontaneously clear the virus within six months of infection without any treatment. More...

Banna Virus Detected by Reverse Transcription-Loop-Mediated Isothermal Amplification

Banna virus (BAV) has been isolated from a diverse group of vertebrates and invertebrates, including mosquitos, ticks, midges, cattle, and pigs from different regions in China, Vietnam, and Indonesia. BAV is considered to be an emerging pathogen that can result in human infections with possible manifestation of fever and viral encephalitis. More...

Alzheimer's Disease Risk Alleles Profiled in Latino Populations

The apolipoprotein E (APOE) gene encodes three common isoforms known as ε2, ε3, and ε4. These are determined by two single nucleotide polymorphisms (SNPs) that result in amino acid substitutions and associated functional changes in the protein. More...
