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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.35T>C (p.I12T) alteration is located in exon 3 (coding exon 1) of the INTS12 gene. This alteration results from a T to C substitution at nucleotide position 35, causing the isoleucine (I) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
