Genes affected

MDFIC (HGNC:28870): (MyoD family inhibitor domain containing) This gene product is a member of a family of proteins characterized by a specific cysteine-rich C-terminal domain, which is involved in transcriptional regulation of viral genome expression. Alternative translation initiation from an upstream non-AUG (GUG), and an in-frame, downstream AUG codon, results in the production of two isoforms, p40 and p32, respectively, which have different subcellular localization; p32 is mainly found in the cytoplasm, whereas p40 is targeted to the nucleolus. Both isoforms have transcriptional regulatory activity that is attributable to the cysteine-rich C-terminal domain. Alternative splicing results in multiple transcript variants.

The c.104T>A (p.V35D) alteration is located in exon 1 (coding exon 1) of the MDFIC gene. This alteration results from a T to A substitution at nucleotide position 104, causing the valine (V) at amino acid position 35 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
