Ambry Genetics

Aug 30, 2021

The c.380G>A (p.C127Y) alteration is located in exon 5 (coding exon 4) of the SWT1 gene. This alteration results from a G to A substitution at nucleotide position 380, causing the cysteine (C) at amino acid position 127 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
