The c.213C>G (p.D71E) alteration is located in exon 1 (coding exon 1) of the ARGLU1 gene. This alteration results from a C to G substitution at nucleotide position 213, causing the aspartic acid (D) at amino acid position 71 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
