The c.1007G>A (p.R336K) alteration is located in exon 9 (coding exon 9) of the CCDC125 gene. This alteration results from a G to A substitution at nucleotide position 1007, causing the arginine (R) at amino acid position 336 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
