The c.440G>C (p.R147P) alteration is located in exon 5 (coding exon 5) of the RTFDC1 gene. This alteration results from a G to C substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
