Ambry Genetics

Sep 17, 2021

The c.220G>A (p.G74R) alteration is located in exon 1 (coding exon 1) of the PLEKHG4B gene. This alteration results from a G to A substitution at nucleotide position 220, causing the glycine (G) at amino acid position 74 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
