Identification of 613 new loci associated with heel bone mineral density and a polygenic risk score for bone mineral density, osteoporosis and fracture - Unknown journal (n.d.) · Unknown authors · PubMed 30048462
ABSTRACT: Low bone mineral density (BMD) leads to osteoporosis, and is a risk factor for bone fractures, including stress fractures. Using data from UK Biobank, a genome-wide association study identified 1,362 independent SNPs that clustered into 899 loci of which 613 are new. These data were used to train a genetic algorithm using 22,886 SNPs as predictors and showing a correlation with heel bone mineral density of 0.415. Combining this genetic algorithm with height, weight, age and sex resulted in a correlation with heel bone mineral density of 0.496. Individuals with low scores (2.2% of total) showed a change in BMD of -1.16 T-score units, an increase in risk for osteoporosis of 17.4 fold and an increase in risk for fracture of 1.87 fold. Genetic predictors could assist in the identific

An atlas of genetic influences on osteoporosis in humans and mice - Unknown journal (n.d.) · Unknown authors · PubMed 30598549
ABSTRACT: Osteoporosis is a common aging-related disease diagnosed primarily using bone mineral density (BMD). We assessed genetic determinants of BMD as estimated by heel quantitative ultrasound (eBMD) in 426,824 individuals, identifying 518 genome-wide significant loci (301 novel), explaining 20% of its variance. We identified 13 bone fracture loci, all associated with eBMD, in ~1.2M individuals. We then identified target genes enriched for genes known to influence bone density and strength (maximum odds-ratio=58, p=10-75) from cell-specific features, including chromatin conformation and accessible chromatin sites. We next performed rapid-throughput skeletal phenotyping of 126 knockout mice lacking target genes and found an increased abnormal skeletal phenotype frequency compared to 526

Lifestyle context
Concrete actions anchored to the cited research. We do not prescribe, we describe.
Exercise
-
resistance and weight-bearing exercise High
Mechanical loading stimulates osteoblasts and improves bone mineral density, directly counteracting the genetic risk associated with ARSB variants.
Resistance training 2-3x/week; weight-bearing activities most days of week
Screening
-
bone mineral density assessment High
Genetic variants in ARSB significantly reduce heel bone mineral density, increasing fracture risk; periodic assessment identifies individuals needing intervention.
DXA scan at age 50 or earlier if additional risk factors; repeat every 1-2 years
Supplements
-
calcium supplementation High
Adequate calcium intake supports bone mineralization in individuals with genetic predisposition to low bone mineral density.
1000-1200 mg/day elemental calcium
-
vitamin D3 supplementation High
Vitamin D enables calcium absorption and is essential for bone mineralization, particularly in those with ARSB variants affecting BMD.
1000-2000 IU daily; target 25-OH vitamin D level 30-50 ng/mL
