Genes affected

INTS3 (HGNC:26153): (integrator complex subunit 3) The protein encoded by this gene can form a complex with human single-strand DNA binding proteins 1 or 2 (hSSB1 and hSSB2) and other proteins to mediate genome stability and the DNA damage response. The encoded protein is also part of a multiprotein complex that interacts with the C-terminal domain of RNA polymerase II large subunit to help regulate processing of U1 and U2 small nuclear RNAs.

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.29).
• BP7: Synonymous conserved (PhyloP=-0.795 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 15 AD gene.
