Collection Method: clinical testing

The c.1069A>C (p.K357Q) alteration is located in exon 9 (coding exon 8) of the CCDC13 gene. This alteration results from a A to C substitution at nucleotide position 1069, causing the lysine (K) at amino acid position 357 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
