Ambry Genetics

Oct 26, 2022

The c.205G>C (p.E69Q) alteration is located in exon 3 (coding exon 3) of the CCDC12 gene. This alteration results from a G to C substitution at nucleotide position 205, causing the glutamic acid (E) at amino acid position 69 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
