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]

Ambry Genetics

Aug 23, 2021

The c.828G>C (p.K276N) alteration is located in exon 6 (coding exon 6) of the OSGIN2 gene. This alteration results from a G to C substitution at nucleotide position 828, causing the lysine (K) at amino acid position 276 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
