Ambry Genetics

Sep 16, 2021

The c.695G>A (p.R232H) 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 695, causing the arginine (R) at amino acid position 232 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
