Genes affected

TFEC (HGNC:11754): (transcription factor EC) This gene encodes a member of the micropthalmia (MiT) family of basic helix-loop-helix leucine zipper transcription factors. MiT transcription factors regulate the expression of target genes by binding to E-box recognition sequences as homo- or heterodimers, and play roles in multiple cellular processes including survival, growth and differentiation. The encoded protein is a transcriptional activator of the nonmuscle myosin II heavy chain-A gene, and may also co-regulate target genes in osteoclasts as a heterodimer with micropthalmia-associated transcription factor. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

Ambry Genetics

Jan 23, 2024

The c.190G>A (p.V64I) alteration is located in exon 3 (coding exon 2) of the TFEC gene. This alteration results from a G to A substitution at nucleotide position 190, causing the valine (V) at amino acid position 64 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
