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.

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage

This sequence change creates a premature translational stop signal at codon 237 (p.Gln237*) of the NR2F2 gene. It is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, truncating variants in NR2F2 are not necessarily pathogenic (PMID: 24702954), and the clinical significance of this variant is uncertain at this time. For these reasons, it has been classified as a Variant of Uncertain Significance. -
