To read the full abstract: J Clin Invest 2018;128:1913-1918Two rare genetic forms of vitamin D–dependent rickets exist: VDDR-1 caused by mutations in the genes encoding either the renal 1-α hydroxylase (CYP27B1: VDDR-1A) or the hepatic 25-hydroxylase (CYP2R1: VDDR-1B) and VDDR-2 caused by mutations in the vitamin D receptor signalling due to mutations in the gene encoding the ...

In Brief: Prolonged bisphosphonate treatment is associated with atypical femoral fractures (AFF). However, AFFs also occur in bisphosphonate-naïve patients, so bisphosphonate is not a prerequisite for AFF. This study found a higher yield of (likely) pathogenic variants in AFF patients with a clinical suspicion of monogenic bone disorder, stressing the importance of careful clinical evaluation of patients who present with this condition.Commentary: A...

In Brief: This is a timely and well-written review on disorders of biomineralization and their fundamental mechanisms and by leading experts in the field. This is mandatory reading for any aspiring endocrinologist.Commentary: Biomineralization is a critical physiological process, and deviations from it can cause various diseases. Recent progress has furthered our understanding of the genetic, molecular, and cellular underpinnings of the disorders of biom...
