Genes affected

HLF (HGNC:4977): (HLF transcription factor, PAR bZIP family member) This gene encodes a member of the proline and acidic-rich (PAR) protein family, a subset of the bZIP transcription factors. The encoded protein forms homodimers or heterodimers with other PAR family members and binds sequence-specific promoter elements to activate transcription. Chromosomal translocations fusing portions of this gene with the E2A gene cause a subset of childhood B-lineage acute lymphoid leukemias. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 22, 2024

The c.133G>A (p.D45N) alteration is located in exon 2 (coding exon 2) of the HLF gene. This alteration results from a G to A substitution at nucleotide position 133, causing the aspartic acid (D) at amino acid position 45 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
