Genes affected
MDFI (HGNC:6967): (MyoD family inhibitor) This protein is a transcription factor that negatively regulates other myogenic family proteins. Studies of the mouse homolog, I-mf, show that it interferes with myogenic factor function by masking nuclear localization signals and preventing DNA binding. Knockout mouse studies show defects in the formation of vertebrae and ribs that also involve cartilage formation in these structures. [provided by RefSeq, Jul 2008]

The c.129C>A (p.H43Q) alteration is located in exon 3 (coding exon 2) of the MDFI gene. This alteration results from a C to A substitution at nucleotide position 129, causing the histidine (H) at amino acid position 43 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
