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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_003120.3. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 11-47355298-GCTT-G is Pathogenic according to our data. Variant chr11-47355298-GCTT-G is described in ClinVar as [Pathogenic]. Clinvar id is 3341205.Status of the report is no_assertion_criteria_provided, 0 stars.
