Paraoxonase 1 (PON1) is reported to have antioxidant and cardioprotective properties. In patients undergoing diagnostic coronary angiography, Bhattacharyya and colleagues investigated the relationship between PON1 genotypes and their functional activity with measures of oxidative stress and CVD risk. The authors found that PON1 gene polymorphisms were associated with low levels of PON1 activity, increased levels of markers of oxidative stress, and increased risks of prevalent CVD and adverse cardiac events.

In a prospective multicenter study involving 37 534 European patients, van Meurs and colleagues examined the association of 2 common variants of the low-density lipoprotein receptor–related protein 5 (LRP5) gene and 1 variant of the LRP6 gene with bone mineral density (BMD) and fracture risk. The authors found that the 2 LRP5 gene variants were consistently associated with BMD and fracture risk.

Binder and colleagues investigated the potential interaction of the stress-related gene FKBP5 with environmental factors including child abuse and other trauma exposure in the expression of adult posttraumatic stress disorder (PTSD) symptoms. The authors identified 4 single-nucleotide polymorphisms of FKBP5 that interacted with the severity of child abuse and predicted the level of PTSD symptoms in adults.

In analyses of pooled DNA samples from 3 case-control studies of unrelated patients with a first deep vein thrombosis (DVT), Bezemer and colleaguesArticle identified single-nucleotide polymorphisms (SNPs) in several genes that were consistently and modestly associated with DVT risk. In an editorial, BovillArticle discusses advances in genotyping and data analysis that will facilitate clinically relevant risk prediction.

Persons with Li-Fraumeni syndrome (LFS) are at risk of diverse and early onset malignancies; thus, effective screening strategies are needed. Masciari and colleagues performed whole-body fluorodeoxyglucose F18–PET/CT in 15 asymptomatic individuals from LFS kindreds and identified asymptomatic cancers in 3 persons.

In a systematic review, Scheuner and colleagues examine what is known about the current status of genetic health services for common adult-onset diseases and the barriers impeding the translation of basic and clinical science advances in genomics into practice.
