Genes affected

TCF21 (HGNC:11632): (transcription factor 21) TCF21 encodes a transcription factor of the basic helix-loop-helix family. The TCF21 product is mesoderm specific, and expressed in embryonic epicardium, mesenchyme-derived tissues of lung, gut, gonad, and both mesenchymal and glomerular epithelial cells in the kidney. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 26, 2022

The c.412G>A (p.D138N) alteration is located in exon 1 (coding exon 1) of the TCF21 gene. This alteration results from a G to A substitution at nucleotide position 412, causing the aspartic acid (D) at amino acid position 138 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
