The c.862G>T (p.V288L) alteration is located in exon 10 (coding exon 8) of the AKR1B15 gene. This alteration results from a G to T substitution at nucleotide position 862, causing the valine (V) at amino acid position 288 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
