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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2022The c.334C>T (p.L112F) alteration is located in exon 2 (coding exon 2) of the TCF23 gene. This alteration results from a C to T substitution at nucleotide position 334, causing the leucine (L) at amino acid position 112 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
