Genes affected

YEATS2 (HGNC:25489): (YEATS domain containing 2) Summary: The protein encoded by this gene is a scaffolding subunit of the ATAC complex, which is a complex with acetyltransferase activity on histones H3 and H4. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2017]

The c.3809C>G (p.A1270G) alteration is located in exon 28 (coding exon 27) of the YEATS2 gene. This alteration results from a C to G substitution at nucleotide position 3809, causing the alanine (A) at amino acid position 1270 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
