Genes affected

OSGIN1 (HGNC:30093): (oxidative stress induced growth inhibitor 1) This gene encodes an oxidative stress response protein that regulates cell death. Expression of the gene is regulated by p53 and is induced by DNA damage. The protein regulates apoptosis by inducing cytochrome c release from mitochondria. It also appears to be a key regulator of both inflammatory and anti-inflammatory molecules. The loss of this protein correlates with uncontrolled cell growth and tumor formation. Naturally occurring read-through transcription exists between this gene and the neighboring upstream malonyl-CoA decarboxylase (MLYCD) gene, but the read-through transcripts are unlikely to produce a protein product.

The c.821C>T (p.A274V) alteration is located in exon 6 (coding exon 5) of the OSGIN1 gene. This alteration results from a C to T substitution at nucleotide position 821, causing the alanine (A) at amino acid position 274 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
