Genes affected

CIDEB (HGNC:1977): (cell death inducing DFFA like effector b) Enables identical protein binding activity. Involved in activation of cysteine-type endopeptidase activity; positive regulation of cell death; and positive regulation of release of cytochrome c from mitochondria. Acts upstream of or within apoptotic process. Located in cytosol and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

NOP9 (HGNC:19826): (NOP9 nucleolar protein) Enables RNA binding activity. Predicted to be involved in ribosome biogenesis. Predicted to be part of 90S preribosome and preribosome, small subunit precursor. Predicted to be active in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

LTB4R2 (HGNC:19260): (leukotriene B4 receptor 2) Predicted to enable G protein-coupled peptide receptor activity and leukotriene B4 receptor activity. Predicted to be involved in inflammatory response and neuropeptide signaling pathway. Predicted to act upstream of or within keratinocyte migration and signal transduction. Located in nucleoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.
