Genes affected

INTS4 (HGNC:25048): (integrator complex subunit 4) INTS4 is a subunit of the Integrator complex, which associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A; MIM 180660) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 180680) and U2 (RNU2; MIM 180690) (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]

May 18, 2023

The c.2354C>T (p.P785L) alteration is located in exon 20 (coding exon 20) of the INTS4 gene. This alteration results from a C to T substitution at nucleotide position 2354, causing the proline (P) at amino acid position 785 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
