Collection Method: clinical testing

The c.205C>T (p.R69W) alteration is located in exon 1 (coding exon 1) of the RNPEPL1 gene. This alteration results from a C to T substitution at nucleotide position 205, causing the arginine (R) at amino acid position 69 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
