The c.359A>G (p.E120G) alteration is located in exon 5 (coding exon 5) of the DBNL gene. This alteration results from a A to G substitution at nucleotide position 359, causing the glutamic acid (E) at amino acid position 120 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
