The c.935G>A (p.R312Q) alteration is located in exon 9 (coding exon 9) of the NARFL gene. This alteration results from a G to A substitution at nucleotide position 935, causing the arginine (R) at amino acid position 312 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
