Ambry Genetics

Dec 27, 2023

The c.2090G>A (p.R697H) alteration is located in exon 13 (coding exon 13) of the CCDC191 gene. This alteration results from a G to A substitution at nucleotide position 2090, causing the arginine (R) at amino acid position 697 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
