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 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 21 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-96332186-G-GCC is Pathogenic according to our data. Variant chr15-96332186-G-GCC is described in ClinVar as [Likely_pathogenic]. Clinvar id is 547880.Status of the report is criteria_provided_single_submitter, 1 stars.
