The c.211G>C (p.V71L) alteration is located in exon 2 (coding exon 2) of the FBP2 gene. This alteration results from a G to C substitution at nucleotide position 211, causing the valine (V) at amino acid position 71 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
