Actionable Genotypes and Their Association with Life Span in Iceland.
Brynjar O Jensson et al. N Engl J Med 2023 11 (19) 1741-1752

From the abstract: " In 2021, the American College of Medical Genetics and Genomics (ACMG) recommended reporting actionable genotypes in 73 genes associated with diseases for which preventive or therapeutic measures are available. Evaluations of the association of actionable genotypes in these genes with life span are currently lacking. In this study, we found that approximately 1 in 25 Icelanders carried an actionable genotype and that carrying such a genotype was associated with a reduced life span."

Modernizing Federal Oversight of Laboratory-Developed Tests - Toward Safety, Validity, and Utility.
Udit Singhal et al. N Engl J Med 2023 11 (19) 1735-1737

From the paper: "Advances in precision medicine have fueled an evolution in the availability of laboratory-developed tests (LDTs). Defined as in vitro diagnostic tests that are “designed, manufactured, and used in a single laboratory,” LDTs were initially conceived as simple tests offered to limited, local groups of patients.1 But LDTs have grown in complexity, and some hospital and commercial laboratories now accept specimens from around the world. "

A software tool to adjust codeine dose based on CYP2D6 gene-pair polymorphisms and drug-drug interactions.
Yolande Saab et al. Pharmacogenomics J 2023 11

From the abstract: "Codeine is metabolized by the CYP2D6 enzyme, and individuals with certain genetic variations of the CYP2D6 gene may metabolize codeine differently, leading to variable efficacy and toxicity. Drug-drug interactions can also affect the metabolism of codeine. A tool to adjust codeine dose based on these factors does not currently exist. Healthcare providers should use their clinical judgment and reference different established dosing guidelines to determine the appropriate dose of codeine for individual patients. The study provides a tool that assists prescribers in adjusting codeine dose based on CYP2D6 gene-pair polymorphisms and drug-drug interactions. "
