Entrez Gene Summary for LRPAP1 Gene

  • This gene encodes a protein that interacts with the low density lipoprotein (LDL) receptor-related protein and facilitates its proper folding and localization by preventing the binding of ligands. Mutations in this gene have been identified in individuals with myopia 23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

GeneCards Summary for LRPAP1 Gene

LRPAP1 (Low Density Lipoprotein Receptor-Related Protein Associated Protein 1) is a Protein Coding gene.
