The c.2863T>C (p.S955P) alteration is located in exon 17 (coding exon 17) of the IGDCC4 gene. This alteration results from a T to C substitution at nucleotide position 2863, causing the serine (S) at amino acid position 955 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
