Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2023The c.350G>A (p.R117Q) alteration is located in exon 1 (coding exon 1) of the MRGPRG gene. This alteration results from a G to A substitution at nucleotide position 350, causing the arginine (R) at amino acid position 117 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
