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.

NECAB2 (HGNC:23746): (N-terminal EF-hand calcium binding protein 2) The protein encoded by this gene is a neuronal calcium-binding protein that binds to and modulates the function of at least two receptors, adenosine A(2A) receptor and metabotropic glutamate receptor type 5. [provided by RefSeq, Jul 2016]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.
