Genes affected

INTS12 (HGNC:25067): (integrator complex subunit 12) INTS12 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]

The c.1333A>G (p.M445V) alteration is located in exon 8 (coding exon 6) of the INTS12 gene. This alteration results from a A to G substitution at nucleotide position 1333, causing the methionine (M) at amino acid position 445 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
