Genes affected

TCF15 (HGNC:11627): (transcription factor 15) The protein encoded by this gene is found in the nucleus and may be involved in the early transcriptional regulation of patterning of the mesoderm. The encoded basic helix-loop-helix protein requires dimerization with another basic helix-loop-helix protein for efficient DNA binding. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.256C>G (p.Q86E) alteration is located in exon 1 (coding exon 1) of the TCF15 gene. This alteration results from a C to G substitution at nucleotide position 256, causing the glutamine (Q) at amino acid position 86 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
