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

Oct 22, 2021

The c.56A>G (p.Y19C) alteration is located in exon 1 (coding exon 1) of the HLF gene. This alteration results from a A to G substitution at nucleotide position 56, causing the tyrosine (Y) at amino acid position 19 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
