Ambry Genetics

May 26, 2024

The c.880T>C (p.S294P) alteration is located in exon 8 (coding exon 6) of the ECT2L gene. This alteration results from a T to C substitution at nucleotide position 880, causing the serine (S) at amino acid position 294 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
