Genes affected

KAT2A (HGNC:4201): (lysine acetyltransferase 2A) KAT2A, or GCN5, is a histone acetyltransferase (HAT) that functions primarily as a transcriptional activator. It also functions as a repressor of NF-kappa-B (see MIM 164011) by promoting ubiquitination of the NF-kappa-B subunit RELA (MIM 164014) in a HAT-independent manner (Mao et al., 2009 [PubMed 19339690]).[supplied by OMIM, Sep 2009]

The c.929G>A (p.R310H) alteration is located in exon 6 (coding exon 6) of the KAT2A gene. This alteration results from a G to A substitution at nucleotide position 929, causing the arginine (R) at amino acid position 310 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
