Genes affected
TCF23 (HGNC:18602): (transcription factor 23) The gene encodes a member of the basic helix-loop-helix transcription factor family. Studies of the orthologous gene in mouse have shown the encoded protein does not bind DNA but may negatively regulate other basic helix-loop-helix factors via the formation of a functionally inactive heterodimeric complex.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 16, 2021 | The c.398G>A (p.G133D) alteration is located in exon 2 (coding exon 2) of the TCF23 gene. This alteration results from a G to A substitution at nucleotide position 398, causing the glycine (G) at amino acid position 133 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
