Genes affected

STARD10 (HGNC:10666): (StAR related lipid transfer domain containing 10) Predicted to enable lipid binding activity. Predicted to be involved in lipid transport. Predicted to act upstream of or within bile acid secretion and positive regulation of peroxisome proliferator activated receptor signaling pathway. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ARAP1 (HGNC:16925): (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 1) The protein encoded by this gene contains SAM, ARF-GAP, RHO-GAP, ankyrin repeat, RAS-associating, and pleckstrin homology (PH) domains. In vitro, this protein displays RHO-GAP and phosphatidylinositol (3,4,5) trisphosphate (PIP3)-dependent ARF-GAP activity. The encoded protein associates with the Golgi, and the ARF-GAP activity mediates changes in the Golgi and the formation of filopodia. It is thought to regulate the cell-specific trafficking of a receptor protein involved in apoptosis. Multiple transcript variants encoding different isoforms have been found for this gene.
