Ambry Genetics

May 20, 2024

The c.730A>G (p.K244E) alteration is located in exon 6 (coding exon 6) of the CCDC138 gene. This alteration results from a A to G substitution at nucleotide position 730, causing the lysine (K) at amino acid position 244 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
