Advances in research on the relationship between the LMNA gene and human diseases (Review)

The LMNA gene, which is responsible for encoding lamin A/C proteins, is recognized as a primary constituent of the nuclear lamina. This protein serves crucial roles in various cellular physiological activities, including the maintenance of cellular structural stability, regulation of gene expression, mechanosensing and cellular motility. A significant association has been established between the LMNA gene and several major human diseases. Mutations, dysregulated expression of the LMNA gene, and improper processing of its encoded protein can result in a spectrum of pathological conditions. These diseases, collectively termed laminopathies, are directly attributed to LMNA gene dysfunction. The present review examines the recent advancements in research concerning the LMNA gene and its association with human diseases, while exploring its pathological roles. Particular emphasis is placed on the current status of LMNA gene research in the context of tumors. This includes an analysis of the abundance of LMNA alterations in cancer and its interplay with various signaling pathways. The aim of the present review was to provide novel perspectives for studying the development of LMNA‑related diseases and additional theoretical insights for basic and clinical translational research in this field.
