Ambry Genetics

Apr 23, 2024

The c.654C>G (p.F218L) alteration is located in exon 3 (coding exon 3) of the RNPEP gene. This alteration results from a C to G substitution at nucleotide position 654, causing the phenylalanine (F) at amino acid position 218 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
