The c.1211G>C (p.C404S) alteration is located in exon 11 (coding exon 10) of the RNFT2 gene. This alteration results from a G to C substitution at nucleotide position 1211, causing the cysteine (C) at amino acid position 404 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
