The c.970C>G (p.L324V) alteration is located in exon 11 (coding exon 10) of the CCDC149 gene. This alteration results from a C to G substitution at nucleotide position 970, causing the leucine (L) at amino acid position 324 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
