Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.494G>A (p.S165N) alteration is located in exon 2 (coding exon 1) of the NPY2R gene. This alteration results from a G to A substitution at nucleotide position 494, causing the serine (S) at amino acid position 165 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
