Lipoid proteinosis (LP) is a rare autosomal recessive multisystem disorder that is caused by loss‐of‐function pathogenic variants in the extracellular matrix protein‐1 (ECM1) gene. The typical clinical manifestations of LP include hoarseness of voice, beaded papules on the eyelids, infiltration and scarring of the skin and mucosa, as well as neuropsychological abnormalities. Currently, more than 70 pathogenic variants have been reported, including nonsense, missense, splice site, deletion and insertion pathogenic variants, and more than half of them occurred in exons 6 and 7.
