Ambry Genetics

May 24, 2023

The c.97G>T (p.G33W) alteration is located in exon 1 (coding exon 1) of the TMED8 gene. This alteration results from a G to T substitution at nucleotide position 97, causing the glycine (G) at amino acid position 33 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
