Genes affected

NIBAN2 (HGNC:25282): (niban apoptosis regulator 2) Enables transcription coactivator activity. Involved in several processes, including gonadotropin secretion; positive regulation of transcription regulatory region DNA binding activity; and regulation of cellular macromolecule biosynthetic process. Located in several cellular components, including adherens junction; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.
