Genes affected

SPI1 (HGNC:11241): (Spi-1 proto-oncogene) 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. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.18871427).
• BP6: Variant 11-47355457-C-T is Benign according to our data. Variant chr11-47355457-C-T is described in ClinVar as [Benign]. Clinvar id is 3341187.Status of the report is no_assertion_criteria_provided, 0 stars.
