Genes affected

ZMYND8 (HGNC:9397): (zinc finger MYND-type containing 8) The protein encoded by this gene is a receptor for activated C-kinase (RACK) protein. The encoded protein has been shown to bind in vitro to activated protein kinase C beta I. In addition, this protein is a cutaneous T-cell lymphoma-associated antigen. Finally, the protein contains a bromodomain and two zinc fingers, and is thought to be a transcriptional regulator. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.2977G>A (p.V993M) alteration is located in exon 19 (coding exon 19) of the ZMYND8 gene. This alteration results from a G to A substitution at nucleotide position 2977, causing the valine (V) at amino acid position 993 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
