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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.649A>T (p.I217F) alteration is located in exon 4 (coding exon 4) of the C1QTNF3 gene. This alteration results from a A to T substitution at nucleotide position 649, causing the isoleucine (I) at amino acid position 217 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
