Ambry Genetics

May 10, 2024

The c.1025A>G (p.N342S) alteration is located in exon 2 (coding exon 1) of the LTB4R2 gene. This alteration results from a A to G substitution at nucleotide position 1025, causing the asparagine (N) at amino acid position 342 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
