Collection Method: clinical testing

The c.1040A>G (p.N347S) alteration is located in exon 5 (coding exon 5) of the RNPEP gene. This alteration results from a A to G substitution at nucleotide position 1040, causing the asparagine (N) at amino acid position 347 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
