Ambry Genetics

Nov 03, 2023

The c.337G>A (p.G113R) alteration is located in exon 3 (coding exon 3) of the TLDC2 gene. This alteration results from a G to A substitution at nucleotide position 337, causing the glycine (G) at amino acid position 113 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
