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]

The c.386G>A (p.R129Q) 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 386, causing the arginine (R) at amino acid position 129 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
