The c.550T>C (p.C184R) alteration is located in exon 5 (coding exon 3) of the CCDC157 gene. This alteration results from a T to C substitution at nucleotide position 550, causing the cysteine (C) at amino acid position 184 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
