[Cutaneous aplasia, non compaction of the left ventricle and severe cardiac arrhythmia: a new case of MLS syndrome (microphtalmia with linear skin defects)].

A female neonate presented with cutaneous aplasia located to the face and the neck associated with a non compaction of the left ventricle leading to the diagnosis of MLS syndrome (microphtalmia with linear skin defects). The follow-up was complicated by life-threatening cardiac arrhythmia underlying prevention by an early diagnosis and adequate care. MLS syndrome and non compaction of myocardium are both located on X chromosome.
