Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.559C>T (p.R187C) alteration is located in exon 3 (coding exon 2) of the MRGPRF gene. This alteration results from a C to T substitution at nucleotide position 559, causing the arginine (R) at amino acid position 187 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
