Genes affected
EZH2 (HGNC:3527): (enhancer of zeste 2 polycomb repressive complex 2 subunit) This gene encodes a member of the Polycomb-group (PcG) family. PcG family members form multimeric protein complexes, which are involved in maintaining the transcriptional repressive state of genes over successive cell generations. This protein associates with the embryonic ectoderm development protein, the VAV1 oncoprotein, and the X-linked nuclear protein. This protein may play a role in the hematopoietic and central nervous systems. Multiple alternatively splcied transcript variants encoding distinct isoforms have been identified for this gene.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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), EZH2. . Gene score misZ 4.6808 (greater than the threshold 3.09). Trascript score misZ 5.1095 (greater than threshold 3.09). GenCC has associacion of gene with Weaver syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.2473656).

Weaver syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJun 29, 2018This sequence change replaces leucine with phenylalanine at codon 363 of the EZH2 protein (p.Leu363Phe). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is present in population databases (rs781431240, ExAC 0.001%). This variant has not been reported in the literature in individuals with EZH2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
