Genes affected

CPSF6 (HGNC:13871): (cleavage and polyadenylation specific factor 6) The protein encoded by this gene is one subunit of a cleavage factor required for 3' RNA cleavage and polyadenylation processing. The interaction of the protein with the RNA is one of the earliest steps in the assembly of the 3' end processing complex and facilitates the recruitment of other processing factors. The cleavage factor complex is composed of four polypeptides. This gene encodes the 68kD subunit. It has a domain organization reminiscent of spliceosomal proteins. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.3056125).
• BS2: High AC in GnomAdExome4 at 9 AD gene.

The c.916C>G (p.P306A) alteration is located in exon 6 (coding exon 6) of the CPSF6 gene. This alteration results from a C to G substitution at nucleotide position 916, causing the proline (P) at amino acid position 306 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
