Ambry Genetics

Mar 08, 2024

The c.680C>T (p.A227V) alteration is located in exon 7 (coding exon 6) of the SPOPL gene. This alteration results from a C to T substitution at nucleotide position 680, causing the alanine (A) at amino acid position 227 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
