The c.1826A>G (p.H609R) alteration is located in exon 11 (coding exon 11) of the DNER gene. This alteration results from a A to G substitution at nucleotide position 1826, causing the histidine (H) at amino acid position 609 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
