A Diagnostic Conundrum in Fumarase Deficiency: Expanding the Clinical and Genetic Spectrum in a Cohort of Pediatric and Adult Patients.

Recognizing new patterns in a rare genetic disease could help doctors diagnose affected families sooner and offer better genetic counseling.

This cohort study expanded the clinical and genetic spectrum of fumarase deficiency, identifying previously unrecognized presentations that complicate diagnosis of this ultra-rare metabolic disease. The findings could aid in earlier recognition and genetic counseling for affected families.

What the study was

Study design
Retrospective cohort (case series with clinical/genetic analysis)
Population
Pediatric and adult patients with fumarase deficiency (ultra-rare autosomal recessive metabolic disease)
Category
Genomics/Precision Medicine
Maturity
Exploratory
Journal
