Ambry Genetics

May 11, 2022

The c.545G>T (p.C182F) alteration is located in exon 7 (coding exon 7) of the DAW1 gene. This alteration results from a G to T substitution at nucleotide position 545, causing the cysteine (C) at amino acid position 182 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
