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]

The c.767A>C (p.D256A) alteration is located in exon 12 (coding exon 11) of the TLE6 gene. This alteration results from a A to C substitution at nucleotide position 767, causing the aspartic acid (D) at amino acid position 256 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
