The c.3392A>G (p.Y1131C) alteration is located in exon 16 (coding exon 15) of the AKNA gene. This alteration results from a A to G substitution at nucleotide position 3392, causing the tyrosine (Y) at amino acid position 1131 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
