The c.1958G>T (p.G653V) alteration is located in exon 14 (coding exon 13) of the CCDC114 gene. This alteration results from a G to T substitution at nucleotide position 1958, causing the glycine (G) at amino acid position 653 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
