To read the full abstract: J Endocr Soc 2017;1:1006-1011Besides its structural role in the extracellular matrix, aggrecan orchestrates a plethora of key mechanisms in endochondral ossification, such as embryonic morphogen distribution, regular indian hedgehog (IHH) / Sox9 expression and columnar chondrocyte orientation. Thus, homozygous loss-of-function mutations in the ACAN gene, encoding...

Genet Med. 2021 Dec;23(12):2443-2447.Abstract: https://pubmed-ncbi-nlm-nih-gov.proxy.kib.ki.se/34341520/In brief: In achondroplasia, longitudinal bone growth is inhibited resulting in severe, disproportionate short stature. In this open-label extension study of participants from the phase 3 study, daily subcutaneous injection of vosoritide during 104 weeks resulted in increa...

In Brief: Individuals with achondroplasia carry a lifelong burden of reduced physical and mental health. The Lifetime Impact of Achondroplasia Study in Europe (LIAISE; NCT03449368) found that, across an individualÂ’s lifetime, achondroplasia is associated with multisystem complications, reduced QoL and functionality, increased pain and increased healthcare resource utilization.Commentary: Individuals with achondroplasia present with a range of clinic...

Lancet. 2020 Sep 5;396(10252):684–692. Abstract: https://pubmed.ncbi.nlm.nih.gov/32891212/In brief: Activating mutations in FGFR3 inhibit endochondral ossification in achondroplasia resulting in disproportionate extreme short stature. In this randomised, double-blind, phase 3, placebo-controlled trial, once-daily subcutaneous treatment with vosoritide, a C-type natriuretic pep...
