Ambry Genetics

Apr 28, 2022

The c.40G>A (p.G14R) alteration is located in exon 1 (coding exon 1) of the TMEM163 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the glycine (G) at amino acid position 14 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
