Ambry Genetics

Sep 22, 2021

The c.667G>A (p.G223S) alteration is located in exon 6 (coding exon 6) of the GRTP1 gene. This alteration results from a G to A substitution at nucleotide position 667, causing the glycine (G) at amino acid position 223 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
