The c.973G>C (p.A325P) alteration is located in exon 2 (coding exon 1) of the LTB4R gene. This alteration results from a G to C substitution at nucleotide position 973, causing the alanine (A) at amino acid position 325 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
