Genes affected

NIBAN1 (HGNC:16784): (niban apoptosis regulator 1) This gene encodes a member of the family with sequence similarity 129 protein family. This gene is highly expressed in several cancer cells and may serve as a prognostic marker for certain cancers. The encoded protein may play a role in regulating p53-mediated apoptosis.

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06328359).

The c.2077G>C (p.E693Q) alteration is located in exon 14 (coding exon 14) of the FAM129A gene. This alteration results from a G to C substitution at nucleotide position 2077, causing the glutamic acid (E) at amino acid position 693 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
