Ambry Genetics

May 30, 2023

The c.26T>G (p.L9R) alteration is located in exon 1 (coding exon 1) of the RWDD3 gene. This alteration results from a T to G substitution at nucleotide position 26, causing the leucine (L) at amino acid position 9 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
