Genes affected

NR2F2 (HGNC:7976): (nuclear receptor subfamily 2 group F member 2) This gene encodes a member of the steroid thyroid hormone superfamily of nuclear receptors. The encoded protein is a ligand inducible transcription factor that is involved in the regulation of many different genes. Alternate splicing results in multiple transcript variants.

The c.43+1G>A variant in the NR2F2 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The c.43+1G>A splice site variant destroys the canonical splice donor site in intron 1. It is predicted to cause abnormal gene splicing, either leading to an abnormal message that is subject to nonsense-mediated mRNA decay, or to an abnormal protein product if the message is used for protein translation. However, this variant occurs in an alternate transcript of NR2F2 where no disease-associated variants have been reported. We interpret c.43+1G>A as variant of uncertain significance. -
