Genes affected

PLAAT3 (HGNC:17825): (phospholipase A and acyltransferase 3) Enables N-acyltransferase activity; phospholipase A1 activity; and phospholipase A2 activity. Involved in N-acylphosphatidylethanolamine metabolic process. Predicted to be located in several cellular components, including lysosome; nuclear envelope; and peroxisome. Predicted to be active in cytoplasm. Biomarker of seminoma. [provided by Alliance of Genome Resources, Apr 2022]
