Ambry Genetics

Sep 14, 2022

The c.139G>A (p.G47R) alteration is located in exon 2 (coding exon 1) of the C1QTNF9 gene. This alteration results from a G to A substitution at nucleotide position 139, causing the glycine (G) at amino acid position 47 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
