Ambry Genetics

Oct 03, 2024

The c.670A>G (p.R224G) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a A to G substitution at nucleotide position 670, causing the arginine (R) at amino acid position 224 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
