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	Warning: this variant incorporates a premature truncation of the aminoacid sequence at residue 052, and may result in misfolding and/or complete absence of the enzyme. 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	Heikkinen et al. identified this mutation in a British patient with Ehlers-Danlos Syndrome (EDS VIA). The abnormal alleles lead to a markedly decreased lysyl-hydroxylase mRNA levels.
Structural Observations   An evaluation of the possible effects/implications of the mutations on the LH1 molecular structure	On homologous LH3, this mutation maps to a glycosylation site on the GT domain of the enzyme. However, this glycosylation site is not predicted to be conserved in LH1.
