Genes affected

AZI2 (HGNC:24002): (5-azacytidine induced 2) AZI2, or NAP1, contributes to the activation of NFKB (see MIM 164011)-dependent gene expression by activating IKK-related kinases, such as NAK (TBK1; MIM 604834) (Fujita et al., 2003 [PubMed 14560022]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Feb 10, 2022

The c.800G>T (p.G267V) alteration is located in exon 8 (coding exon 7) of the AZI2 gene. This alteration results from a G to T substitution at nucleotide position 800, causing the glycine (G) at amino acid position 267 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
