Genes affected

LEF1 (HGNC:6551): (lymphoid enhancer binding factor 1) This gene encodes a transcription factor belonging to a family of proteins that share homology with the high mobility group protein-1. The protein encoded by this gene can bind to a functionally important site in the T-cell receptor-alpha enhancer, thereby conferring maximal enhancer activity. This transcription factor is involved in the Wnt signaling pathway, and it may function in hair cell differentiation and follicle morphogenesis. Mutations in this gene have been found in somatic sebaceous tumors. This gene has also been linked to other cancers, including androgen-independent prostate cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

The c.305A>G (p.Y102C) alteration is located in exon 3 (coding exon 3) of the LEF1 gene. This alteration results from a A to G substitution at nucleotide position 305, causing the tyrosine (Y) at amino acid position 102 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
