The c.989C>G (p.A330G) alteration is located in exon 13 (coding exon 11) of the IFT46 gene. This alteration results from a C to G substitution at nucleotide position 989, causing the alanine (A) at amino acid position 330 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
