Genes affected

LOX (HGNC:6664): (lysyl oxidase) This gene encodes a member of the lysyl oxidase family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate a regulatory propeptide and the mature enzyme. The copper-dependent amine oxidase activity of this enzyme functions in the crosslinking of collagens and elastin, while the propeptide may play a role in tumor suppression. In addition, defects in this gene have been linked with predisposition to thoracic aortic aneurysms and dissections. [provided by RefSeq, Jul 2016]

SRFBP1 (HGNC:26333): (serum response factor binding protein 1) Enables RNA binding activity. Predicted to be involved in maturation of SSU-rRNA. Predicted to be located in perinuclear region of cytoplasm. Predicted to be part of 90S preribosome. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
