Genes affected

PRPF18 (HGNC:17351): (pre-mRNA processing factor 18) Pre-mRNA splicing occurs in 2 sequential transesterification steps. The protein encoded by this gene is found to be essential for the catalytic step II in pre-mRNA splicing process. It is found in the spliceosome, and contains seven WD repeats, which function in protein-protein interactions. This protein has a sequence similarity to the yeast splicing factor Prp18.

Ambry Genetics

Sep 14, 2023

The c.71A>G (p.N24S) alteration is located in exon 2 (coding exon 2) of the PRPF18 gene. This alteration results from a A to G substitution at nucleotide position 71, causing the asparagine (N) at amino acid position 24 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
