Abstract

With growing reports of severe presentations in children, increasing our genetic understanding of pulmonary alveolar microlithiasis (PAM) is crucial. We describe a 6-month-old infant presenting with bronchiolitis, with deterioration due to disseminated Pseudomonas infection, with novel homozygosity of a variant in SLC34A2, and with pulmonary calcospherites on postmortem analysis, in keeping with PAM.
