Ambry Genetics

Dec 16, 2023

The c.586A>C (p.K196Q) alteration is located in exon 5 (coding exon 5) of the CCDC43 gene. This alteration results from a A to C substitution at nucleotide position 586, causing the lysine (K) at amino acid position 196 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
