The c.1312T>C (p.S438P) alteration is located in exon 9 (coding exon 9) of the RFTN2 gene. This alteration results from a T to C substitution at nucleotide position 1312, causing the serine (S) at amino acid position 438 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
