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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2900712).

Ambry Genetics

Nov 02, 2023

The c.613G>A (p.V205I) 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 613, causing the valine (V) at amino acid position 205 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
