Ambry Genetics

May 09, 2023

The c.406G>A (p.D136N) alteration is located in exon 5 (coding exon 5) of the TMEM255B gene. This alteration results from a G to A substitution at nucleotide position 406, causing the aspartic acid (D) at amino acid position 136 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
