The c.1200A>G (p.I400M) alteration is located in exon 11 (coding exon 11) of the CCDC91 gene. This alteration results from a A to G substitution at nucleotide position 1200, causing the isoleucine (I) at amino acid position 400 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
