The c.655C>A (p.P219T) alteration is located in exon 5 (coding exon 2) of the CCDC102B gene. This alteration results from a C to A substitution at nucleotide position 655, causing the proline (P) at amino acid position 219 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
