A locus on chromosome 1p36 is associated with thyrotropin and thyroid function as identified by genome-wide association study.

Thyroid hormones are key regulators of cellular growth, development, and metabolism, and thyroid disorders are a common cause of ill health in the community. Circulating concentrations of thyrotropin (TSH), thyroxine (T4) and triiodothyronine (T3) have a strong heritable component and are thought to be under polygenic control, but the genes responsible are mostly unknown. In order to identify genetic loci associated with these metabolic phenotypes, we performed a genome-wide association study of 2,120,505 SNPs in 2014 female twins from the TwinsUK study and found a significant association between rs10917469 on chromosome 1p36.

A comparative study between corresponding structural geometric variables using 2 commonly implemented hip structural analysis algorithms applied to dual-energy X-ray absorptiometry images.

Hip structural analysis (HSA) has been developed over 20 yr, applied extensively in research, and has demonstrated useful outcomes associating bone structural geometry with bone fragility (research-HSA or r-HSA). In 2007, Hologic Inc. (Bedford, MA) incorporated HSA with some modifications as an option for Hologic dual-energy X-ray absorptiometry (DXA) scanners (clinical HSA or c-HSA).
