The c.238C>G (p.Q80E) alteration is located in exon 2 (coding exon 1) of the LTB4R gene. This alteration results from a C to G substitution at nucleotide position 238, causing the glutamine (Q) at amino acid position 80 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
