Genes affected

KAT7 (HGNC:17016): (lysine acetyltransferase 7) The protein encoded by this gene is part of the multimeric HBO1 complex, which possesses histone H4-specific acetyltransferase activity. This activity is required for functional replication origins and is involved in transcriptional activation of some genes. In both cases, the acetylation of histone H4 helps unfold chromatin so that the DNA can be accessed and replicated or transcribed. [provided by RefSeq, Oct 2016]

The c.398C>T (p.A133V) alteration is located in exon 4 (coding exon 4) of the KAT7 gene. This alteration results from a C to T substitution at nucleotide position 398, causing the alanine (A) at amino acid position 133 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
