Genes affected

LTB4R2 (HGNC:19260): (leukotriene B4 receptor 2) Predicted to enable G protein-coupled peptide receptor activity and leukotriene B4 receptor activity. Predicted to be involved in inflammatory response and neuropeptide signaling pathway. Predicted to act upstream of or within keratinocyte migration and signal transduction. Located in nucleoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

LTB4R2 links:

CIDEB (HGNC:1977): (cell death inducing DFFA like effector b) Enables identical protein binding activity. Involved in activation of cysteine-type endopeptidase activity; positive regulation of cell death; and positive regulation of release of cytochrome c from mitochondria. Acts upstream of or within apoptotic process. Located in cytosol and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 27, 2022

The c.125T>C (p.V42A) alteration is located in exon 2 (coding exon 1) of the LTB4R2 gene. This alteration results from a T to C substitution at nucleotide position 125, causing the valine (V) at amino acid position 42 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
