The c.202A>G (p.R68G) alteration is located in exon 3 (coding exon 3) of the NREP gene. This alteration results from a A to G substitution at nucleotide position 202, causing the arginine (R) at amino acid position 68 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
