Genes affected

PRDM14 (HGNC:14001): (PR/SET domain 14) This gene encodes a member of the PRDI-BF1 and RIZ homology domain containing (PRDM) family of transcriptional regulators. The encoded protein may possess histone methyltransferase activity and plays a critical role in cell pluripotency by suppressing the expression of differentiation marker genes. Expression of this gene may play a role in breast cancer. [provided by RefSeq, Dec 2011]

The c.161G>A (p.R54Q) alteration is located in exon 2 (coding exon 1) of the PRDM14 gene. This alteration results from a G to A substitution at nucleotide position 161, causing the arginine (R) at amino acid position 54 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
