Genes affected

TLE1 (HGNC:11837): (TLE family member 1, transcriptional corepressor) Enables identical protein binding activity and transcription corepressor activity. Involved in negative regulation of I-kappaB kinase/NF-kappaB signaling; negative regulation of anoikis; and regulation of gene expression. Located in cytosol and nucleoplasm. Part of beta-catenin-TCF complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.2011T>C (p.W671R) alteration is located in exon 18 (coding exon 18) of the TLE1 gene. This alteration results from a T to C substitution at nucleotide position 2011, causing the tryptophan (W) at amino acid position 671 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
