Ambry Genetics

Oct 29, 2021

The c.149G>A (p.R50Q) alteration is located in exon 4 (coding exon 2) of the GNG4 gene. This alteration results from a G to A substitution at nucleotide position 149, causing the arginine (R) at amino acid position 50 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
