Genes affected

YAF2 (HGNC:17363): (YY1 associated factor 2) This gene encodes a zinc finger containing protein that functions in the regulation of transcription. This protein was identified as an interacting partner of transcriptional repressor protein Yy1, and also interacts with other transcriptional regulators, including Myc and Polycomb. This protein can promote proteolysis of Yy1. Multiple alternatively spliced transcript variants have been found. [provided by RefSeq, Feb 2016]

The c.493A>G (p.S165G) alteration is located in exon 5 (coding exon 5) of the YAF2 gene. This alteration results from a A to G substitution at nucleotide position 493, causing the serine (S) at amino acid position 165 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
