Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 28, 2023The c.169G>T (p.D57Y) alteration is located in exon 1 (coding exon 1) of the MRGPRG gene. This alteration results from a G to T substitution at nucleotide position 169, causing the aspartic acid (D) at amino acid position 57 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
