Genes affected
ZIC3 (HGNC:12874): (Zic family member 3) This gene encodes a member of the ZIC family of C2H2-type zinc finger proteins. This nuclear protein probably functions as a transcription factor in early stages of left-right body axis formation. Mutations in this gene cause X-linked visceral heterotaxy, which includes congenital heart disease and left-right axis defects in organs. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 12, 2023 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with ZIC3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Leu37Ilefs*21) in the ZIC3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ZIC3 are known to be pathogenic (PMID: 24123890). - |
