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]

The c.1217A>G (p.Y406C) alteration is located in exon 10 (coding exon 10) of the FAM129B gene. This alteration results from a A to G substitution at nucleotide position 1217, causing the tyrosine (Y) at amino acid position 406 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
