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.456A>G (p.I152M) alteration is located in exon 3 (coding exon 3) of the MDFIC gene. This alteration results from a A to G substitution at nucleotide position 456, causing the isoleucine (I) at amino acid position 152 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
