Genes affected
CHD7 (HGNC:20626): (chromodomain helicase DNA binding protein 7) This gene encodes a protein that contains several helicase family domains. Mutations in this gene have been found in some patients with the CHARGE syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 16, 2018 | For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Gln814*) in the CHD7 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with CHD7-related disease (PMID: 23885230, 29300383) and has been reported to be de novo in an individual referred for CHARGE syndrome genetic testing (PMID: 21158681). ClinVar contains an entry for this variant (Variation ID: 488369). Loss-of-function variants in CHD7 are known to be pathogenic (PMID: 22461308, 25077900). - |
