Case in brief
This report details two siblings with compound heterozygous mutations in the FLAD1 gene, resulting in adrenal insufficiency, a previously unreported association. The mutations A418V and R542* were confirmed through a personalized mouse model, which replicated the patients' physiological and biochemical symptoms, establishing a causal link between FLAD1 mutations and adrenal steroidogenesis impairment.
Diagnostic / clinical pearl
Clinicians should consider FLAD1 gene mutations as a potential cause of adrenal insufficiency, especially in familial cases.
Why it matters
Understanding the role of FLAD1 mutations in adrenal insufficiency may enhance diagnostic accuracy and inform future therapeutic strategies.
