Ambry Genetics

Jul 09, 2024

The c.255G>C (p.W85C) alteration is located in exon 2 (coding exon 1) of the PRPF39 gene. This alteration results from a G to C substitution at nucleotide position 255, causing the tryptophan (W) at amino acid position 85 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
