Collection Method:clinical testing

The c.2354A>G (p.D785G) alteration is located in exon 15 (coding exon 14) of the AKNAD1 gene. This alteration results from a A to G substitution at nucleotide position 2354, causing the aspartic acid (D) at amino acid position 785 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
