Nov 10, 2022

The c.1456A>G (p.R486G) alteration is located in exon 6 (coding exon 5) of the NXPE4 gene. This alteration results from a A to G substitution at nucleotide position 1456, causing the arginine (R) at amino acid position 486 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
