Ambry Genetics

Apr 12, 2022

The c.922T>G (p.C308G) alteration is located in exon 8 (coding exon 8) of the UBE3C gene. This alteration results from a T to G substitution at nucleotide position 922, causing the cysteine (C) at amino acid position 308 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
