The c.643T>C (p.S215P) alteration is located in exon 3 (coding exon 3) of the SDF2L1 gene. This alteration results from a T to C substitution at nucleotide position 643, causing the serine (S) at amino acid position 215 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
