Pearson marrow-pancreas syndrome is a rare multisystem mitochondrial disease that is a result of defective oxidative phosphorylation caused by mitochondrial DNA mutations. The average prognosis of infants diagnosed with this disease is death within four years of age. The disease often carries an atypical presentation during the neonatal period causing this rare syndrome to be frequently misdiagnosed. The current report details the diagnosis of Pearson syndrome in a three-month-old male with a history of pancytopenia.

This piece narrates the journey of Maria (name of the mother has been altered to protect the family's privacy), a new mother confronting her newborn's unexpected diagnosis of very long chain acyl-CoA dehydrogenase (VLCAD) deficiency, despite undergoing proactive genetic carrier screening within a consanguineous marriage. It highlights the emotional and systemic challenges arising from the lack of diversity in genetic databases, which, in this case, failed to detect pathogenic variants in Maria and her husband. Maria's story sheds light on situations where a masked variant of uncertain significance (VUS) necessitates consultation with a trained genetics specialist and underscores the urgent need for a more equitable healthcare system.

Very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency is a rare genetic condition affecting the mitochondrial beta-oxidation of long-chain fatty acids. This study reports on the clinical outcomes of patients diagnosed by newborn screening with VLCAD deficiency comparing metabolic parameters, enzyme activities, molecular results, and clinical management. It is a single-center retrospective chart review of VLCAD deficiency patients who met the inclusion criteria between January 2002 and February 2020.
