Ambry Genetics

Feb 13, 2024

The c.631G>C (p.G211R) alteration is located in exon 7 (coding exon 7) of the TM6SF2 gene. This alteration results from a G to C substitution at nucleotide position 631, causing the glycine (G) at amino acid position 211 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
