Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PM2PM5PP3_ModeratePP5_Very_Strong

The NM_001273.5(CHD4):c.3203G>A(p.Arg1068His) 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 Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1068S) has been classified as Likely pathogenic.

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]
