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 Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.445C>T (p.P149S) alteration is located in exon 3 (coding exon 3) of the PCF11 gene. This alteration results from a C to T substitution at nucleotide position 445, causing the proline (P) at amino acid position 149 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
