The c.811G>T (p.V271L) alteration is located in exon 2 (coding exon 1) of the NPY2R gene. This alteration results from a G to T substitution at nucleotide position 811, causing the valine (V) at amino acid position 271 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
