The c.196A>T (p.I66L) alteration is located in exon 2 (coding exon 2) of the CEP126 gene. This alteration results from a A to T substitution at nucleotide position 196, causing the isoleucine (I) at amino acid position 66 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
