The c.1490G>A (p.R497H) alteration is located in exon 12 (coding exon 12) of the IFRD2 gene. This alteration results from a G to A substitution at nucleotide position 1490, causing the arginine (R) at amino acid position 497 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
