Ambry Genetics

Feb 06, 2023

The c.1349C>T (p.S450L) alteration is located in exon 8 (coding exon 8) of the ECE2 gene. This alteration results from a C to T substitution at nucleotide position 1349, causing the serine (S) at amino acid position 450 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
