The c.2125G>A (p.A709T) alteration is located in exon 13 (coding exon 13) of the DNER gene. This alteration results from a G to A substitution at nucleotide position 2125, causing the alanine (A) at amino acid position 709 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
