Genes affected

QRICH1 (HGNC:24713): (glutamine rich 1) Enables DNA binding activity. Involved in several processes, including PERK-mediated unfolded protein response; intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress; and positive regulation of transcription, DNA-templated. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
