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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.167G>A (p.R56Q) alteration is located in exon 2 (coding exon 2) of the HEBP1 gene. This alteration results from a G to A substitution at nucleotide position 167, causing the arginine (R) at amino acid position 56 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
