Genes affected

NR0B2 (HGNC:7961): (nuclear receptor subfamily 0 group B member 2) The protein encoded by this gene is an unusual orphan receptor that contains a putative ligand-binding domain but lacks a conventional DNA-binding domain. The gene product is a member of the nuclear hormone receptor family, a group of transcription factors regulated by small hydrophobic hormones, a subset of which do not have known ligands and are referred to as orphan nuclear receptors. The protein has been shown to interact with retinoid and thyroid hormone receptors, inhibiting their ligand-dependent transcriptional activation. In addition, interaction with estrogen receptors has been demonstrated, leading to inhibition of function. Studies suggest that the protein represses nuclear hormone receptor-mediated transactivation via two separate steps: competition with coactivators and the direct effects of its transcriptional repressor function.

NR0B2 links:

NUDC (HGNC:8045): (nuclear distribution C, dynein complex regulator) This gene encodes a nuclear distribution protein that plays an essential role in mitosis and cytokinesis. The encoded protein is involved in spindle formation during mitosis and in microtubule organization during cytokinesis. Pseudogenes of this gene are found on chromosome 2.

The NR0B2 c.647G>A variant is predicted to result in the amino acid substitution p.Arg216His. This variant was previously reported in an individual with hypertriglyceridemia (Matsunaga et al. 2020. PubMed ID: 32115487). This variant was also described in an individual with mild obesity; however, the authors suggested that it may be a benign polymorphism (Nishigori et al. 2001. PubMed ID: 11136233). Additionally, several in vitro studies indicated that protein with the p.Arg216His change functioned similar to control (Sanyal et al. 2002. PubMed ID: 11705994). This variant is reported in 0.040% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
