Collection Method: clinical testing

The c.2023G>A (p.E675K) alteration is located in exon 17 (coding exon 17) of the NAALADL1 gene. This alteration results from a G to A substitution at nucleotide position 2023, causing the glutamic acid (E) at amino acid position 675 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
