Genes affected

HAT1 (HGNC:4821): (histone acetyltransferase 1) The protein encoded by this gene is a type B histone acetyltransferase (HAT) that is involved in the rapid acetylation of newly synthesized cytoplasmic histones, which are in turn imported into the nucleus for de novo deposition onto nascent DNA chains. Histone acetylation, particularly of histone H4, plays an important role in replication-dependent chromatin assembly. Specifically, this HAT can acetylate soluble but not nucleosomal histone H4 at lysines 5 and 12, and to a lesser degree, histone H2A at lysine 5. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Jun 2009]

The c.1063A>G (p.I355V) alteration is located in exon 10 (coding exon 10) of the HAT1 gene. This alteration results from a A to G substitution at nucleotide position 1063, causing the isoleucine (I) at amino acid position 355 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
