Genomic-First Approach Offers Potential for Earlier Diagnosis of Rare Disorders

A "genomic-first" approach to screening for rare genetic disorders -identifying specific genetic variants and then studying associated traits and symptoms - can identify these conditions earlier and more frequently than standard genetic testing driven by clinical symptoms, a Geisinger study found.

PNPLA3 Gene Variant Linked to Liver Injury After Chemotherapy in Colorectal Cancer Patients

A new international study led by Mayo Clinic researchers has identified a genetic factor that may explain why some patients with colorectal cancer that has spread to the liver experience more severe liver damage after chemotherapy.

Chromosome Zippers Rely on DNA Junctions to Safeguard Fertility

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over.
