The c.1498G>C (p.G500R) alteration is located in exon 1 (coding exon 1) of the KLHL34 gene. This alteration results from a G to C substitution at nucleotide position 1498, causing the glycine (G) at amino acid position 500 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
