A recent study using integrated bioinformatics analysis for expression and methylation of exocytosis genes from The Cancer Genome Atlas Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (TCGA-CESC) dataset identified ATP8B4 as one of nine genes linked with metastasis in cervical carcinoma [53]. The gene discussed is ATP8B4; the disease is cervical squamous cell carcinoma.
