The c.1849G>T (p.V617L) alteration is located in exon 11 (coding exon 10) of the AKNAD1 gene. This alteration results from a G to T substitution at nucleotide position 1849, causing the valine (V) at amino acid position 617 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
