US Patent 11883470 Compositions comprising a lecithin cholesterol acyltransferase variant and uses thereof

A synthetic or recombinant human lecithin cholesterol acyltransferase (LCAT) variant is provided which comprises an LCAT enzyme having a substitution at position 114 based on the residue numbering of wild-type (WT) human LCAT [SEQ ID NO:1], wherein said variant is characterized by one or more of: (i) an esterification rate higher than the esterification rate of WT human LCAT; and/or (ii) an association with higher density lipoprotein levels as compared to subjects having WT LCAT. Also provided are vectors encoding the variant, compositions containing same, and methods of using the variant proteins and vectors for treatment of a variety of disorders associated with defective wt LCAT.
