The c.1308G>C (p.K436N) alteration is located in exon 5 (coding exon 4) of the CCDC181 gene. This alteration results from a G to C substitution at nucleotide position 1308, causing the lysine (K) at amino acid position 436 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
