FGD4 and cancer: According to the results of this study, by a series of bioinformatics analysis methods, we screened out six potential biomarkers correlated with SCI, including “LIN7A,” “FCGR1A,” “FGD4,” “GPR27,” “BLOC1S1,” and “GALNT4.” LIN7A is wellstudied in malignant tumors, such as breast carcinomas, ovarian cancer, and hepatocellular carcinoma (17–19), whose encoded protein is a small scaffold protein related to PDZ domain binding and L27 domain binding.
