Collection Method: clinical testing

The c.71A>G (p.K24R) alteration is located in exon 2 (coding exon 2) of the CCDC94 gene. This alteration results from a A to G substitution at nucleotide position 71, causing the lysine (K) at amino acid position 24 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
