The c.4223C>T (p.A1408V) alteration is located in exon 22 (coding exon 21) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 4223, causing the alanine (A) at amino acid position 1408 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
