Genes affected

OSGIN2 (HGNC:1355): (oxidative stress induced growth inhibitor family member 2) Predicted to enable growth factor activity. Predicted to be involved in negative regulation of cell growth. [provided by Alliance of Genome Resources, Apr 2022]

OSGIN2 links:

NBN (HGNC:7652): (nibrin) Mutations in this gene are associated with Nijmegen breakage syndrome, an autosomal recessive chromosomal instability syndrome characterized by microcephaly, growth retardation, immunodeficiency, and cancer predisposition. The encoded protein is a member of the MRE11/RAD50 double-strand break repair complex which consists of 5 proteins. This gene product is thought to be involved in DNA double-strand break repair and DNA damage-induced checkpoint activation. [provided by RefSeq, Jul 2008]
