The c.1296A>G (p.I432M) alteration is located in exon 16 (coding exon 14) of the CCDC7 gene. This alteration results from a A to G substitution at nucleotide position 1296, causing the isoleucine (I) at amino acid position 432 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
