Identifying the Probable Etiology of Acute Undifferentiated Fever through Inflammatory Markers.

Background: Acute undifferentiated fever (AUF) is defined as any febrile illness with a duration of ≤14 days without evidence of localized infection. Most outpatient services and a significant inpatient load in India are contributed by AUF. COVID-19 has recently added to the existing list of common etiologies of AUF.

Novel RNASEH2C mutation in multiple members of a large family: insights into phenotypic spectrum of Aicardi-Goutières Syndrome.

Background: Aicardi-Goutières syndrome (AGS) is a genetic inflammatory disorder that presents with early infantile encephalopathy. We report the clinical and molecular details of multiple members of a family with AGS secondary to a novel RNASEH2C mutation, highlighting the evolution of phenotypic abnormalities in AGS.

Methods: Between February 2018 and June 2019, a pedigree tree was constructed for 141 members of a family.
