Ambry Genetics

Sep 06, 2022

The c.626G>A (p.R209Q) 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 626, causing the arginine (R) at amino acid position 209 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
