The c.3833G>T (p.G1278V) alteration is located in exon 20 (coding exon 19) of the AKNA gene. This alteration results from a G to T substitution at nucleotide position 3833, causing the glycine (G) at amino acid position 1278 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
