Genes affected

INTS4 (HGNC:25048): (integrator complex subunit 4) INTS4 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]

AAMDC (HGNC:30205): (adipogenesis associated Mth938 domain containing) Predicted to be involved in positive regulation of fat cell differentiation. Predicted to act upstream of or within negative regulation of apoptotic process and positive regulation of transcription by RNA polymerase II. Predicted to be active in cytoplasm.

The c.2449A>G (p.I817V) alteration is located in exon 21 (coding exon 21) of the INTS4 gene. This alteration results from a A to G substitution at nucleotide position 2449, causing the isoleucine (I) at amino acid position 817 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
