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]

ENSG00000285238 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 15 ACMG points.

• PM1: In a domain Helicase C-terminal (size 149) in uniprot entity CHD4_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_001273.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the CHD4 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 48 curated pathogenic missense variants (we use a threshold of 10). The gene has 33 curated benign missense variants. Gene score misZ: 6.3412 (above the threshold of 3.09). Trascript score misZ: 8.6114 (above the threshold of 3.09). GenCC associations: The gene is linked to syndromic intellectual disability, Sifrim-Hitz-Weiss syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.913
• PP5: Variant 12-6591713-C-T is Pathogenic according to our data. Variant chr12-6591713-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 266124.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-6591713-C-T is described in Lovd as [Pathogenic].
