Genes affected

C1QTNF3 (HGNC:14326): (C1q and TNF related 3) Enables identical protein binding activity. Involved in several processes, including cellular triglyceride homeostasis; negative regulation of NIK/NF-kappaB signaling; and regulation of cytokine production. Acts upstream of or within negative regulation of gluconeogenesis. Located in extracellular exosome and membrane. [provided by Alliance of Genome Resources, Apr 2022]

C1QTNF3-AMACR (HGNC:49198): (C1QTNF3-AMACR readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring C1q and tumor necrosis factor related protein 3 (C1QTNF3) and alpha-methylacyl-CoA racemase (AMACR) genes on chromosome 5. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus not likely to produce a protein product. [provided by RefSeq, Mar 2011]

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 (BayesDel_noAF=-0.85).
