Genes affected

ACER3 (HGNC:16066): (alkaline ceramidase 3) Enables N-acylsphingosine amidohydrolase activity and metal ion binding activity. Involved in several processes, including myelination; positive regulation of cell population proliferation; and sphingolipid metabolic process. Is integral component of Golgi membrane and integral component of endoplasmic reticulum membrane. Biomarker of hepatocellular carcinoma and non-alcoholic steatohepatitis.
