The c.379G>A (p.G127R) alteration is located in exon 4 (coding exon 4) of the LCN6 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the glycine (G) at amino acid position 127 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
