Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.807G>C (p.R269S) alteration is located in exon 1 (coding exon 1) of the MRGPRG gene. This alteration results from a G to C substitution at nucleotide position 807, causing the arginine (R) at amino acid position 269 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
