Genes affected

INTS1 (HGNC:24555): (integrator complex subunit 1) INTS1 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]

Ambry Genetics

Nov 08, 2022

The c.6463G>A (p.A2155T) alteration is located in exon 48 (coding exon 47) of the INTS1 gene. This alteration results from a G to A substitution at nucleotide position 6463, causing the alanine (A) at amino acid position 2155 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
