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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.938

Collection Method: clinical testing

The c.1556G>A (p.C519Y) alteration is located in exon 8 (coding exon 7) of the PRDM14 gene. This alteration results from a G to A substitution at nucleotide position 1556, causing the cysteine (C) at amino acid position 519 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
