Genes affected

TBXT (HGNC:11515): (T-box transcription factor T) The protein encoded by this gene is an embryonic nuclear transcription factor that binds to a specific DNA element, the palindromic T-site. It binds through a region in its N-terminus, called the T-box, and effects transcription of genes required for mesoderm formation and differentiation. The protein is localized to notochord-derived cells. Variation in this gene was associated with susceptibility to neural tube defects and chordoma. A mutation in this gene was found in a family with sacral agenesis with vertebral anomalies. [provided by RefSeq, Sep 2018]

The c.1198C>G (p.L400V) alteration is located in exon 9 (coding exon 8) of the T gene. This alteration results from a C to G substitution at nucleotide position 1198, causing the leucine (L) at amino acid position 400 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
