Genes affected

HEBP1 (HGNC:17176): (heme binding protein 1) The full-length protein encoded by this gene is an intracellular tetrapyrrole-binding protein. This protein includes a natural chemoattractant peptide of 21 amino acids at the N-terminus, which is a natural ligand for formyl peptide receptor-like receptor 2 (FPRL2) and promotes calcium mobilization and chemotaxis in monocytes and dendritic cells.

The c.433G>A (p.V145I) alteration is located in exon 4 (coding exon 4) of the HEBP1 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the valine (V) at amino acid position 145 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
