The c.1667A>G (p.Y556C) alteration is located in exon 9 (coding exon 8) of the AKNAD1 gene. This alteration results from a A to G substitution at nucleotide position 1667, causing the tyrosine (Y) at amino acid position 556 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
