Ambry Genetics

Nov 19, 2022

The c.436G>A (p.D146N) alteration is located in exon 6 (coding exon 3) of the GTDC1 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the aspartic acid (D) at amino acid position 146 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
