The c.494A>G (p.Q165R) alteration is located in exon 4 (coding exon 4) of the NCR1 gene. This alteration results from a A to G substitution at nucleotide position 494, causing the glutamine (Q) at amino acid position 165 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
