Genes affected
TCF7L1 (HGNC:11640): (transcription factor 7 like 1) This gene encodes a member of the T cell factor/lymphoid enhancer factor family of transcription factors. These transcription factors are activated by beta catenin, mediate the Wnt signaling pathway and are antagonized by the transforming growth factor beta signaling pathway. The encoded protein contains a high mobility group-box DNA binding domain and participates in the regulation of cell cycle genes and cellular senescence. [provided by RefSeq, Nov 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.498C>G (p.D166E) alteration is located in exon 4 (coding exon 4) of the TCF7L1 gene. This alteration results from a C to G substitution at nucleotide position 498, causing the aspartic acid (D) at amino acid position 166 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
