Ambry Genetics

Sep 26, 2022

The c.2618G>C (p.S873T) alteration is located in exon 22 (coding exon 21) of the EXD3 gene. This alteration results from a G to C substitution at nucleotide position 2618, causing the serine (S) at amino acid position 873 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
