The c.1933A>G (p.R645G) alteration is located in exon 11 (coding exon 11) of the CCDC191 gene. This alteration results from a A to G substitution at nucleotide position 1933, causing the arginine (R) at amino acid position 645 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
