The c.1540G>C (p.G514R) alteration is located in exon 6 (coding exon 5) of the MZF1 gene. This alteration results from a G to C substitution at nucleotide position 1540, causing the glycine (G) at amino acid position 514 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
