Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 08, 2023 | The c.449A>G (p.Y150C) alteration is located in exon 1 (coding exon 1) of the TAS2R20 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the tyrosine (Y) at amino acid position 150 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
