Abstract:
Pediatric recurrent acute liver failure (RALF) with recovery between episodes is rare. Causes include autoimmune disease, which may flare and subside; intermittent exposure to toxins, as with ingestions; and metabolic disorders, among them the fever-associated crises ascribed to biallelic mutations in SCYL1, with RALF beginning in infancy. SCYL1 disease manifest with RALF, as known to date, includes central and peripheral neurologic and muscular morbidity (hepatocerebellar neuropathy syndrome). Primary ventilatory and skeletal diseases also have been noted in some reports. We describe a Han Chinese boy in whom fever-associated RALF began at age 14 mo. Bilateral femoral head abnormalities and mild impairment of neurologic function were first noted aged 8 years 6 mo. Liver biopsy after the third RALF episode (7 years) and during resolution of the fourth RALF episode (8 years 6 mo) found abnormal architecture and hepatic fibrosis, respectively. Whole-exome sequencing revealed homozygosity for the novel frameshift mutation c.92_93insGGGCCCT, p.(H32Gfs*20) in SCYL1 (parental heterozygosity confirmed). Our findings expand the mutational and clinical spectrum of SCYL1 disease. In our patient a substantial neurologic component was lacking and skeletal disease was identified relatively late.
