Leucine-rich repeat-containing protein 4 is a protein that in humans is encoded by the LRRC4 gene.[5][6]

This gene is significantly downregulated in primary brain tumors. The exact function of the protein encoded by this gene is unknown.[6] Also it has been identified as a possible pathogenic gene involved in the neurogenic inflammation in rosacea.[7]
