The c.2587C>T (p.P863S) alteration is located in exon 17 (coding exon 16) of the CEP128 gene. This alteration results from a C to T substitution at nucleotide position 2587, causing the proline (P) at amino acid position 863 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
