Genes affected

JADE3 (HGNC:22982): (jade family PHD finger 3) This gene encodes a member of a family of large proteins containing PHD (plant homeo domain)-type zinc fingers. The encoded protein may be associated in a nuclear complex that functions in histone H4 acetylation. Alternative splicing results in multiple transcript variants encoding the same protein.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32885632).

The c.1384G>A (p.E462K) alteration is located in exon 9 (coding exon 8) of the JADE3 gene. This alteration results from a G to A substitution at nucleotide position 1384, causing the glutamic acid (E) at amino acid position 462 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
