Abstract summary 

Salih myopathy is autosomal recessive hereditary early-onset myopathy with fatal cardiomyopathy. It is a rare and heterogeneous form of congenital titinopathies (TTN). Affected children have delayed motor development, normal mental development, and in further course dilated cardiomyopathy. Motor functions have a tendency to improve, but death occurs most often before 20 years of age due to arrhythmias. Our patient is a 2-year-old girl, born in severe perinatal asphyxia, with global hypotonia and poor spontaneous movements. She required immediate endotracheal intubation and mechanical ventilation was initiated without the possibility of cessation. Improvement in her neurological status was not observed. Due to her clinical presentation, we performed genetic testing and a diagnosis of Salih myopathy caused by combination of two heterozygous TTN mutations was confirmed. This case illustrates that Salih myopathy may have severe presentation from birth, with continuous necessity for mechanical ventilation, without any motor improvement.
