Ambry Genetics

Feb 28, 2024

The c.1123G>C (p.E375Q) alteration is located in exon 14 (coding exon 14) of the CCDC93 gene. This alteration results from a G to C substitution at nucleotide position 1123, causing the glutamic acid (E) at amino acid position 375 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
