Evidence at protein level   Based on available structural and biochemical information, a statement about the existence of an LH enzyme variant bearing the described mutation is provided	This variant is EXTREMELY UNLIKELY to be compatible with a folded LH enzyme. The representation shown in the structure viewer is therefore for mere display purposes and does not refer to an actual predicted existing protein product.

Notes from publications   A curated excerpt with information about the mutation from the publications found above	Walker et al. identified the homozygous mutation T1360>G in an Ehlers-Danlos VIA patient. The mutation was in exon 13 of PLOD1 gene and was predicted to result in an amino acid change Trp446Gly. Through site directed mutagenesis and biochemical analysis the authors confirmed that this mutation causes a decrease in lysyl-hydroxylase activity. This mutation is not in localized in the LH domain, but occurs in a highly conserved region of the accessory domain. Therefore, the loss of activity may be caused by abnormal folding of the enzyme. The Trp446Gly mutation was also reported to cause Ehlers-Danlos VIA in another patient by Yis et al.
