RHNO1

protein-coding

RAD9-HUS1-RAD1 interacting nuclear orphan 1

Gene summary

Enables chromatin-protein adaptor activity. Involved in several processes, including DNA repair; cellular response to radiation; and regulation of cell cycle process. Located in chromosome and nucleus. Is active in chromatin and site of double-strand break. [provided by Alliance of Genome Resources, Jul 2025]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_001252499.3. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Function
FUNCTION: Plays a role in DNA damage response (DDR) signaling upon genotoxic stresses such as ionizing radiation (IR) during the S phase. Recruited to sites of DNA damage through interaction with the 9-1-1 cell-cycle checkpoint response complex and TOPBP1 in a ATR-dependent manner. Required for the progression of the G1 to S phase transition. Plays a role in the stimulation of CHEK1 phosphorylation. {ECO:0000269|PubMed:21659603}.;
