Autozomálně recesivní
Caused by changes in both copies of MYMK (myomaker), and rarely MYMX (myomixer), proteins needed for muscle precursor cells to fuse into muscle fibres. Reduced fusion leads to a congenital myopathy.
Příznaky a projevy
Marked facial weakness, with a small jaw and cleft palate (Pierre Robin sequence), and generalised low muscle tone and weakness are typical. Motor delay and short stature are also reported.
Co se diagnózou změní
Care is tailored to the features present. Parents are usually carriers, so carrier testing for relatives and genetic counselling are available.
