Genes affected
EZH1 (HGNC:3526): (enhancer of zeste 1 polycomb repressive complex 2 subunit) EZH1 is a component of a noncanonical Polycomb repressive complex-2 (PRC2) that mediates methylation of histone H3 (see MIM 602812) lys27 (H3K27) and functions in the maintenance of embryonic stem cell pluripotency and plasticity (Shen et al., 2008 [PubMed 19026780]).[supplied by OMIM, Mar 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.455A>G (p.N152S) alteration is located in exon 6 (coding exon 4) of the EZH1 gene. This alteration results from a A to G substitution at nucleotide position 455, causing the asparagine (N) at amino acid position 152 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
