Genes affected

C1QTNF1 (HGNC:14324): (C1q and TNF related 1) Enables collagen binding activity. Involved in several processes, including negative regulation of platelet aggregation; positive regulation of aldosterone secretion; and positive regulation of cytosolic calcium ion concentration. Located in extracellular space. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
