Genes affected

PCF11 (HGNC:30097): (PCF11 cleavage and polyadenylation factor subunit) The protein encoded by this gene binds to CLP1 to form pre-mRNA cleavage factor IIm. The encoded protein is necessary for efficient Pol II transcription termination and may be involved in degradation of the 3' product of polyA site cleavage. [provided by RefSeq, Oct 2016]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.03432861).

Nov 13, 2024

The c.997A>C (p.I333L) alteration is located in exon 5 (coding exon 5) of the PCF11 gene. This alteration results from a A to C substitution at nucleotide position 997, causing the isoleucine (I) at amino acid position 333 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
