The c.2459G>A (p.R820Q) alteration is located in exon 14 (coding exon 14) of the MICALL2 gene. This alteration results from a G to A substitution at nucleotide position 2459, causing the arginine (R) at amino acid position 820 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
