The c.771C>G (p.I257M) alteration is located in exon 3 (coding exon 3) of the CCDC3 gene. This alteration results from a C to G substitution at nucleotide position 771, causing the isoleucine (I) at amino acid position 257 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
