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]

Ambry Genetics

Feb 03, 2022

The c.100C>T (p.H34Y) alteration is located in exon 2 (coding exon 2) of the SPI1 gene. This alteration results from a C to T substitution at nucleotide position 100, causing the histidine (H) at amino acid position 34 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
