Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 31, 2022The c.443G>A (p.R148Q) 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 443, causing the arginine (R) at amino acid position 148 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
