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 Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NR2F2. . Gene score misZ 3.5964 (greater than the threshold 3.09). Trascript score misZ 4.1992 (greater than threshold 3.09). GenCC has associacion of gene with congenital heart defects, multiple types, 4, NR2F2 related multiple congenital anomalies/dysmorphic syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.30652064).

The c.162G>C (p.Q54H) alteration is located in exon 1 (coding exon 1) of the NR2F2 gene. This alteration results from a G to C substitution at nucleotide position 162, causing the glutamine (Q) at amino acid position 54 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
