To read the full abstract: Proc Natl Acad Sci U S A 2017;114:E11323-E11332The mechanism of thyroid hormone (TH) action is classically attributed to thyroid hormone receptor (THR) binding to thyroid hormone responsive elements (TRE) in promotors of target genes, directly controlling gene expression in target tissues. Thus, THRs alpha (TRa) and beta (TRb) function as TH dependent transcription ...

In Brief: The 11th edition of the ‘Nosology’ is significantly expanded, now covering 771 conditions linked to 552 genes. In a major shift from previous editions, it has adopted a dyadic naming system that defines disorders based on both their phenotypic and genetic features. It continues to be a vital tool for diagnosing and communicating about genetic skeletal disorders.Commentary: The first Nosology of genetic skeletal disorders was published...
