Genes affected

KAT5 (HGNC:5275): (lysine acetyltransferase 5) The protein encoded by this gene belongs to the MYST family of histone acetyl transferases (HATs) and was originally isolated as an HIV-1 TAT-interactive protein. HATs play important roles in regulating chromatin remodeling, transcription and other nuclear processes by acetylating histone and nonhistone proteins. This protein is a histone acetylase that has a role in DNA repair and apoptosis and is thought to play an important role in signal transduction. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The c.79G>A (p.V27I) alteration is located in exon 1 (coding exon 1) of the KAT5 gene. This alteration results from a G to A substitution at nucleotide position 79, causing the valine (V) at amino acid position 27 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
