The c.766C>T (p.R256C) alteration is located in exon 5 (coding exon 5) of the CILP2 gene. This alteration results from a C to T substitution at nucleotide position 766, causing the arginine (R) at amino acid position 256 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
