Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2021The c.509A>G (p.E170G) alteration is located in exon 1 (coding exon 1) of the TAS2R42 gene. This alteration results from a A to G substitution at nucleotide position 509, causing the glutamic acid (E) at amino acid position 170 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
