oculopharyngodistal myopathy (OPDM) is a rare hereditary neuromuscular disease. Its typical clinical manifestations are slowly progressive muscle weakness of extraocular muscles, facial muscles, bulb muscles and distal extremities. For a long time, the pathogenic genes of the disease have been unknown. Searching for the pathogenic genes of OPDM is of great significance for the accurate diagnosis, treatment and pathogenesis of OPDM. In 2019, Japan's Tsuji team first reported that the abnormal repeat amplification of CGG in the 5'UTR region of LRP12 gene was the first causative gene of OPDM. Followed by Wang Chaoxia and Yuan Yun's team from the Department of Neurology, Peking University First Hospital, cooperated with other domestic neuromuscular disease research teams, and reported the abnormal repeat amplification of CGG in the 5'UTR region of two causative genes of OPDM-GIPC1 gene and NOTCH2NLC gene, which have been confirmed by domestic and foreign peers. However, there are still some patients with OPDM whose pathogenic genes are unknown.
