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.

The c.1316G>A (p.R439H) alteration is located in exon 12 (coding exon 12) of the INTS3 gene. This alteration results from a G to A substitution at nucleotide position 1316, causing the arginine (R) at amino acid position 439 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
