The c.365G>A (p.C122Y) alteration is located in exon 3 (coding exon 1) of the NPY4R gene. This alteration results from a G to A substitution at nucleotide position 365, causing the cysteine (C) at amino acid position 122 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
