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]

Feb 05, 2024

The c.1931C>T (p.P644L) alteration is located in exon 14 (coding exon 14) of the FAM129B gene. This alteration results from a C to T substitution at nucleotide position 1931, causing the proline (P) at amino acid position 644 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
