Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.899A>G (p.Q300R) alteration is located in exon 3 (coding exon 2) of the MRGPRF gene. This alteration results from a A to G substitution at nucleotide position 899, causing the glutamine (Q) at amino acid position 300 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
