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]

The c.2255A>G (p.K752R) alteration is located in exon 20 (coding exon 20) of the TLE1 gene. This alteration results from a A to G substitution at nucleotide position 2255, causing the lysine (K) at amino acid position 752 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
