Notes from publications   A curated excerpt with information about the mutation from the publications found above	Giunta et al. studied 9 patients from 12 unrelated families identifying novel mutations causing Ehlers-Danlos syndrome (EDS VIA). Ala667 and His706Arg mutation are respectively caused by the transitions c.1890G>A and c.2008A>G (c.2117A>G). The authors showed that both aminoacids are highly conserved between the three human isoforms (PLOD1, PLOD2, and PLOD3) and across several species (bovine, mouse, rat, chicken, xenopus, fruit fly and C. elegans). The analysis of a control population further identify these mutations as the only responsible for impaired lysyl hydroxylase activity in the two patients under investigation.
