The c.922T>C (p.C308R) alteration is located in exon 9 (coding exon 9) of the CCDC148 gene. This alteration results from a T to C substitution at nucleotide position 922, causing the cysteine (C) at amino acid position 308 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
