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]

ARHGEF38 (HGNC:25968): (Rho guanine nucleotide exchange factor 38) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of catalytic activity. Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ARHGEF38 Gene-Disease associations (from GenCC):

• autism spectrum disorder
