Genes affected

ING3 (HGNC:14587): (inhibitor of growth family member 3) The protein encoded by this gene is similar to ING1, a tumor suppressor protein that can interact with TP53, inhibit cell growth, and induce apoptosis. This protein contains a PHD-finger, which is a common motif in proteins involved in chromatin remodeling. This gene can activate p53 trans-activated promoters, including promoters of p21/waf1 and bax. Overexpression of this gene has been shown to inhibit cell growth and induce apoptosis. Allelic loss and reduced expression of this gene were detected in head and neck cancers. Two alternatively spliced transcript variants encoding different isoforms have been observed.

The c.154A>C (p.K52Q) alteration is located in exon 3 (coding exon 3) of the ING3 gene. This alteration results from a A to C substitution at nucleotide position 154, causing the lysine (K) at amino acid position 52 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
