Abstract

A newborn presented with respiratory insufficiency requiring artificial ventilation, inability to swallow, lack of spontaneous movements including the facial muscles, and areflexia. Nerve conduction velocities were not recordable. Molecular analysis showed a homozygous deletion in the spinal muscular atrophy (SMN) gene region on chromosome 5q. Pathological and neuropathological examination revealed a normal number of anterior horn cells, hypomyelinated axons in peripheral nerves and some atrophy of skeletal muscle fibres in combination with sarcoplasmic glycogen accumulation. This observation illustrates that severe congenital neuropathy can result from deletions in the SMN gene.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
