Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PP2PP3_ModeratePP5

The NM_004456.5(EZH2):​c.2213C>A​(p.Ala738Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A738T) has been classified as Uncertain significance.

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 Likely_pathogenic. Variant got 8 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_004456.5
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.861
PP5
Variant 7-148807689-G-T is Pathogenic according to our data. Variant chr7-148807689-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 430846.Status of the report is no_assertion_criteria_provided, 0 stars.
