Ambry Genetics

May 18, 2023

The c.1178T>G (p.L393W) alteration is located in exon 10 (coding exon 7) of the GTDC1 gene. This alteration results from a T to G substitution at nucleotide position 1178, causing the leucine (L) at amino acid position 393 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
