Genes affected
KAT8 (HGNC:17933): (lysine acetyltransferase 8) This gene encodes a member of the MYST histone acetylase protein family. The encoded protein has a characteristic MYST domain containing an acetyl-CoA-binding site, a chromodomain typical of proteins which bind histones, and a C2HC-type zinc finger. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.133A>G (p.T45A) alteration is located in exon 1 (coding exon 1) of the KAT8 gene. This alteration results from a A to G substitution at nucleotide position 133, causing the threonine (T) at amino acid position 45 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
