Summary
This gene encodes an ETS-domain transcription factor that activates gene expression during myeloid and B-lymphoid cell development. The nuclear protein binds to a purine-rich sequence known as the PU-box found near the promoters of target genes, and regulates their expression in coordination with other transcription factors and cofactors. The protein can also regulate alternative splicing of target genes. Multiple transcript variants encoding different isoforms have been found for this gene.

Variant Counts

Variant classification counts, according to ACMG guideline on all identified variants among our tested samples, are listed. The variants with over 5% variant frequency in population genome databases ( gnomAD, dbSNP, etc.) are excluded.
