C18ORF32

Chr 18AR

chromosome 18 open reading frame 32

Also known as: GPIBD25

The protein activates NF-kappaB signaling and is located in the endoplasmic reticulum and lipid droplets. Autosomal recessive mutations cause glycosylphosphatidylinositol biosynthesis defect 25, though the clinical features remain to be fully characterized. The gene shows low constraint to loss-of-function variation in the general population.
