Ambry Genetics

Apr 28, 2022

The c.2162G>A (p.R721H) alteration is located in exon 1 (coding exon 1) of the CD248 gene. This alteration results from a G to A substitution at nucleotide position 2162, causing the arginine (R) at amino acid position 721 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
