{Reference Type}: Case Reports {Title}: Fatal cervical myelopathy in a child with glutaric aciduria type 1. {Author}: Chauvet E;Ribeiro D;Kern I;Fluss J; {Journal}: J Inherit Metab Dis {Volume}: 47 {Issue}: 2 {Year}: 2024 03 7 {Factor}: 4.75 {DOI}: 10.1002/jimd.12716 {Abstract}: We report the case of a Syrian female refugee with late diagnosis of glutaric aciduria type 1 characterised by massive axial hypotonia and quadriplegia who only started adequate diet upon arrival in Switzerland at the age of 4 years, after a strenuous migration journey. Soon after arrival, she died from an unexpected severe upper cervical myelopathy, heralded by acute respiratory distress after a viral infection. This was likely due to repeated strains on her hypotonic neck and precipitated by an orthotopic os odontoideum who led to atlanto-axial subluxation. This case reminds us not to omit handling patients with insufficient postural control and hypotonia with great care to avoid progressive cervical myelopathy.
