Genes affected
INTS2 (HGNC:29241): (integrator complex subunit 2) INTS2 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.2964T>G (p.C988W) alteration is located in exon 21 (coding exon 21) of the INTS2 gene. This alteration results from a T to G substitution at nucleotide position 2964, causing the cysteine (C) at amino acid position 988 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
