Genes affected

CPSF1 (HGNC:2324): (cleavage and polyadenylation specific factor 1) Cleavage and polyadenylation specificity factor (CPSF) is a multisubunit complex that plays a central role in 3-prime processing of pre-mRNAs. CPSF recognizes the AAUAAA signal in the pre-mRNA and interacts with other proteins to facilitate both RNA cleavage and poly(A) synthesis. CPSF1 is the largest subunit of the CPSF complex (Murthy and Manley, 1995 [PubMed 7590244]).[supplied by OMIM, Mar 2008]

The c.3349C>A (p.L1117I) alteration is located in exon 30 (coding exon 29) of the CPSF1 gene. This alteration results from a C to A substitution at nucleotide position 3349, causing the leucine (L) at amino acid position 1117 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
