Ambry Genetics

May 27, 2022

The c.929T>C (p.I310T) alteration is located in exon 8 (coding exon 8) of the UPP2 gene. This alteration results from a T to C substitution at nucleotide position 929, causing the isoleucine (I) at amino acid position 310 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
