Ambry Genetics

Dec 21, 2023

The c.742C>T (p.R248W) alteration is located in exon 4 (coding exon 4) of the ECE2 gene. This alteration results from a C to T substitution at nucleotide position 742, causing the arginine (R) at amino acid position 248 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
