Collection Method: clinical testing

The c.2982G>T (p.K994N) alteration is located in exon 17 (coding exon 16) of the CCDC73 gene. This alteration results from a G to T substitution at nucleotide position 2982, causing the lysine (K) at amino acid position 994 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
