Genotyping Assay Integrated into Glioma Treatment

Stage II diffuse gliomas are normally challenging to identify using intraoperative histologic methods because of their location, infiltrative growth, low cellularity, and small stereotactic biopsy size. Diagnosis often requires the patient to undergo multiple neurosurgical procedures to collect tumor tissue samples. More...

Blood-Based Test Predicts Benefits of Lung Cancer Treatment

Although programmed death-ligand 1–programmed death 1 (PD-L1–PD-1) inhibitors are broadly efficacious, improved outcomes have been observed in patients with high PD-L1 expression or high tumor mutational burden (TMB). More...

Genetic Mutation Identified in Childhood Brain Disorder

Pachygyria is characterized by abnormal movement of brain nerve cells, known as neurons, during development of the brain and nervous system and is caused by a breakdown in the fetal neuronal migration process due to genetic or possibly environmental influences. More...

Biomarker-Based Blood Test Developed for Early Cancer Diagnosis

A blood test for early detection of kidney cancer is based on the KIM-1 (Kidney-injury-molecule-1) protein biomarker. More...

Genetic Testing for Hypercholesterolemia Improves Diagnosis

Familial Hypercholesterolemia (FH) is caused by a genetic defect that hinders the body's ability to remove low-density lipoprotein (LDL) cholesterol from the blood. High LDL levels in the blood are more likely to result in narrowing of the arteries, which puts patients at substantially higher lifetime risk for heart disease and stroke at an early age. More...

Image: The figure illustrates how T cells are detected in a blood sample with Epiontis ID. In T cells, the CD3 gene region is epigenetically active (yellow); in all other cell types, this region is epigenetically inactive (blue). The number of epigenetically active CD3 gene copies directly translates to the number of T cells in the sample (Photo courtesy of Precision for Medicine).

Epigenetic Diagnostic Tool Detects Diseases in Newborns

Newborns are routinely screened for inheritable diseases by analyzing dried blood spots (DBS) from blood taken from a heel-prick. Among the more than 300 known primary immune deficiencies (PIDs), only Severe Combined Immunodeficiencies (SCID) are detected at birth with the current technology used to analyze the DBS. More...

New Glioma Test Provides Answers during Surgical Procedures

A new diagnostic test detects certain mutations in glioma tumors during brain surgery and identifies those sensitive to metabolic chemotherapeutic agents. More...
