The c.2951A>C (p.D984A) alteration is located in exon 21 (coding exon 20) of the CEP128 gene. This alteration results from a A to C substitution at nucleotide position 2951, causing the aspartic acid (D) at amino acid position 984 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
