Genes affected

CPSF3 (HGNC:2326): (cleavage and polyadenylation specific factor 3) This gene encodes a member of the metallo-beta-lactamase family. The encoded protein is a 73kDa subunit of the cleavage and polyadenylation specificity factor and functions as an endonuclease that recognizes the pre-mRNA 3'-cleavage site AAUAAA prior to polyadenylation. It also cleaves after the pre-mRNA sequence ACCCA during histone 3'-end pre-mRNA processing. [provided by RefSeq, Oct 2012]

CPSF3 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with microcephaly, hypotonia, nystagmus, and seizures

  Inheritance: AR Classification: MODERATE, LIMITED Submitted by: G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

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