Ambry Genetics

Oct 29, 2024

The c.946G>A (p.G316R) alteration is located in exon 2 (coding exon 1) of the LTB4R2 gene. This alteration results from a G to A substitution at nucleotide position 946, causing the glycine (G) at amino acid position 316 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
