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:):

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000711 (932/1310032) while in subpopulation EAS AF= 0.0189 (719/38032). AF 95% confidence interval is 0.0178. There are 5 homozygotes in gnomad4_exome. There are 432 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 5 AR gene
