Ambry Genetics

Nov 10, 2022

The c.176C>G (p.A59G) alteration is located in exon 3 (coding exon 3) of the UPP2 gene. This alteration results from a C to G substitution at nucleotide position 176, causing the alanine (A) at amino acid position 59 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
