Collection Method: clinical testing

The c.77A>G (p.D26G) alteration is located in exon 2 (coding exon 2) of the NAALADL2 gene. This alteration results from a A to G substitution at nucleotide position 77, causing the aspartic acid (D) at amino acid position 26 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
