Genes affected
BRF2 (HGNC:17298): (BRF2 RNA polymerase III transcription initiation factor subunit) This gene encodes one of the multiple subunits of the RNA polymerase III transcription factor complex required for transcription of genes with promoter elements upstream of the initiation site. The product of this gene, a TFIIB-like factor, is directly recruited to the TATA-box of polymerase III small nuclear RNA gene promoters through its interaction with the TATA-binding protein.

ADGRA2 (HGNC:17849): (adhesion G protein-coupled receptor A2) Predicted to enable G protein-coupled receptor activity. Involved in positive regulation of canonical Wnt signaling pathway. Part of Wnt signalosome. [provided by Alliance of Genome Resources, Apr 2022]
