Ambry Genetics

Nov 02, 2021

The c.73G>T (p.G25W) alteration is located in exon 1 (coding exon 1) of the CCDC138 gene. This alteration results from a G to T substitution at nucleotide position 73, causing the glycine (G) at amino acid position 25 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
