Genes affected

INTS11 (HGNC:26052): (integrator complex subunit 11) The Integrator complex contains at least 12 subunits and associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A; MIM 180660) and mediates the 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 180680) and U2 (RNU2; MIM 180690). INTS11, or CPSF3L, is the catalytic subunit of the Integrator complex (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]

INTS11 Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

  Inheritance: AR Classification: MODERATE Submitted by: Ambry Genetics
• neurodevelopmental disorder with motor and language delay, ocular defects, and brain abnormalities

  Inheritance: AR Classification: MODERATE Submitted by: G2P

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BP7: Synonymous conserved (PhyloP=-2.75 with no splicing effect.
