The c.1613G>A (p.R538Q) alteration is located in exon 7 (coding exon 7) of the NUAK2 gene. This alteration results from a G to A substitution at nucleotide position 1613, causing the arginine (R) at amino acid position 538 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
