Genes affected
TLE6 (HGNC:30788): (TLE family member 6, subcortical maternal complex member) This gene encodes a member of the Groucho/ transducin-like Enhancer of split family of transcriptional co-repressors. The encoded protein is a component of the mammalian subcortical maternal complex, which is required for preimplantation development. In mouse, knock out of this gene results in cleavage-stage embryonic arrest resulting from defective cytoplasmic F-actin meshwork formation and asymmetric cell division. In human, an allelic variant in this gene is associated with preimplantation embryonic lethality. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

Pathogenic, criteria provided, single submitterclinical testingInvitaeJul 05, 2022This sequence change creates a premature translational stop signal (p.Ser223Phefs*30) in the TLE6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TLE6 are known to be pathogenic (PMID: 26537248, 29606347, 32172300). This variant is present in population databases (rs765448750, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with TLE6-related conditions. For these reasons, this variant has been classified as Pathogenic. -
