Ambry Genetics

Dec 14, 2023

The c.240C>G (p.S80R) alteration is located in exon 3 (coding exon 2) of the URB2 gene. This alteration results from a C to G substitution at nucleotide position 240, causing the serine (S) at amino acid position 80 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
