Ambry Genetics

Jun 02, 2023

The c.35A>G (p.E12G) alteration is located in exon 1 (coding exon 1) of the TTC17 gene. This alteration results from a A to G substitution at nucleotide position 35, causing the glutamic acid (E) at amino acid position 12 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
