Researchers identified a link between genetic mutations in the ABCA1 gene and lower HDL cholesterol levels in the general population. Approximately 10% of individuals with low HDL levels carry a mutation or nucleotide modification in one of their ABCA1 genes, suggesting that genetic variation plays a role in regulating HDL levels.

New quick test for drug-resistant strains of gonorrhea

A new quick test has been developed to detect drug-resistant strains of gonorrhea by identifying genes linked to resistance in urine samples or leftover products from other diagnostic techniques. The test uses probe technology to simplify analysis of samples that cannot be used for culturing organisms.
