Dec 06, 2023

The c.17C>T (p.S6F) alteration is located in exon 2 (coding exon 1) of the LTB4R gene. This alteration results from a C to T substitution at nucleotide position 17, causing the serine (S) at amino acid position 6 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
