Genes affected

CHD4 (HGNC:1919): (chromodomain helicase DNA binding protein 4) The product of this gene belongs to the SNF2/RAD54 helicase family. It represents the main component of the nucleosome remodeling and deacetylase complex and plays an important role in epigenetic transcriptional repression. Patients with dermatomyositis develop antibodies against this protein. Somatic mutations in this gene are associated with serous endometrial tumors. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a domain Helicase C-terminal (size 149) in uniprot entity CHD4_HUMAN there are 27 pathogenic changes around while only 1 benign (96%) in NM_001273.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, CHD4
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.919
• PP5: Variant 12-6588320-C-A is Pathogenic according to our data. Variant chr12-6588320-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 266128.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr12-6588320-C-A is described in Lovd as [Pathogenic].
