Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_021078.3(KAT2A):​c.1907G>T​(p.Ser636Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S636N) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: KAT2A NM_021078.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.73
• Publications: 0 publications found

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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
