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]

The c.612G>T (p.Q204H) alteration is located in exon 4 (coding exon 4) of the C1QTNF3 gene. This alteration results from a G to T substitution at nucleotide position 612, causing the glutamine (Q) at amino acid position 204 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
