Ambry Genetics

Feb 14, 2024

The c.691C>G (p.L231V) alteration is located in exon 7 (coding exon 7) of the UBE2Q2 gene. This alteration results from a C to G substitution at nucleotide position 691, causing the leucine (L) at amino acid position 231 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
