Collection Method: clinical testing

The c.758C>G (p.P253R) alteration is located in exon 4 (coding exon 4) of the RNPEP gene. This alteration results from a C to G substitution at nucleotide position 758, causing the proline (P) at amino acid position 253 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
