Ambry Genetics

Mar 18, 2024

The c.192G>T (p.W64C) alteration is located in exon 4 (coding exon 3) of the MTX3 gene. This alteration results from a G to T substitution at nucleotide position 192, causing the tryptophan (W) at amino acid position 64 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
