The c.766C>T (p.P256S) alteration is located in exon 10 (coding exon 8) of the IFT46 gene. This alteration results from a C to T substitution at nucleotide position 766, causing the proline (P) at amino acid position 256 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
