Аннотация
An 11-day-old female neonate was admitted for cough with mouth foaming and feeding difficulties. The laboratory results indicated hyperlactatemia, elevated markers of myocardial injury and inflammation, and high levels of acylcarnitine octanoylcarnitine and decanoylcarnitine in tandem mass spectrometry. Ultrasonography and MRI suggested cardiac insufficiency and hypertrophic cardiomyopathy. Whole exome sequencing showed that both the proband and her elderly sister had a compound heterozygous variant of c.1492dup (p.T498Nfs*13) and c.1376T>C (p.F459S) in the ATAD3A gene, inherited from their father and mother, respectively. The diagnosis of Harel-Yoon syndrome was confirmed. The proband and her sister were born with clinical manifestations of metabolic acidosis, hyperlactatemia, feeding difficulties, elevated markers of myocardial injury as well as cardiac insufficiency, and both died in early infancy.
