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 -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.16544989).
• BS2: High AC in GnomAdExome4 at 17 AD gene.

The c.542G>A (p.S181N) alteration is located in exon 4 (coding exon 4) of the PCF11 gene. This alteration results from a G to A substitution at nucleotide position 542, causing the serine (S) at amino acid position 181 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
