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]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.763
• BS2: High AC in GnomAdExome4 at 5 AD gene.

The c.1753G>A (p.D585N) alteration is located in exon 16 (coding exon 16) of the TLE1 gene. This alteration results from a G to A substitution at nucleotide position 1753, causing the aspartic acid (D) at amino acid position 585 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
