Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2023The c.998T>C (p.M333T) alteration is located in exon 3 (coding exon 2) of the MRGPRF gene. This alteration results from a T to C substitution at nucleotide position 998, causing the methionine (M) at amino acid position 333 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
