The c.455A>G (p.E152G) alteration is located in exon 4 (coding exon 4) of the DBNDD1 gene. This alteration results from a A to G substitution at nucleotide position 455, causing the glutamic acid (E) at amino acid position 152 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
