Collection Method: clinical testing

The c.166T>C (p.C56R) alteration is located in exon 3 (coding exon 2) of the CLIP4 gene. This alteration results from a T to C substitution at nucleotide position 166, causing the cysteine (C) at amino acid position 56 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
