Collection Method: clinical testing

The c.814G>C (p.E272Q) alteration is located in exon 7 (coding exon 7) of the CCDC125 gene. This alteration results from a G to C substitution at nucleotide position 814, causing the glutamic acid (E) at amino acid position 272 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
