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]

Ambry Genetics

Nov 07, 2024

The c.131C>T (p.P44L) alteration is located in exon 1 (coding exon 1) of the KAT8 gene. This alteration results from a C to T substitution at nucleotide position 131, causing the proline (P) at amino acid position 44 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
