Genes affected

ETS2 (HGNC:3489): (ETS proto-oncogene 2, transcription factor) This gene encodes a transcription factor which regulates genes involved in development and apoptosis. The encoded protein is also a protooncogene and shown to be involved in regulation of telomerase. A pseudogene of this gene is located on the X chromosome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

ENSG00000205622 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

Oct 16, 2024

The c.680C>G (p.P227R) alteration is located in exon 7 (coding exon 6) of the ETS2 gene. This alteration results from a C to G substitution at nucleotide position 680, causing the proline (P) at amino acid position 227 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
