Gomez-Lopez-Hernandez syndrome: an easily missed diagnosis

Abstract

Gomez-Lopez-Hernandez syndrome (GLHS) is a rare syndrome comprising the triad rhombencephalosynapsis (RS), parietal alopecia, and trigeminal anesthesia. Other typical findings are skull abnormalities, craniofacial dysmorphic signs, and short stature. Intellectual impairment is typical but cases with normal cognitive functions have also been reported. Only 15 cases of GLHS have been described so far, all sporadic. We report four further patients with GLHS: one neonate, two children and a middle aged man. In all cases the diagnosis was made only in retrospect; one child died as neonate due to esophageal atresia. All patients presented RS and parietal alopecia, three intermittent head stereotypies, two had obvious trigeminal anesthesia, and one normal cognition. Alopecia and also trigeminal anesthesia can be very mild and can be easily missed. However, the dysmorphic signs including bilateral alopecia are already present in the neonatal period and are highly suggestive of GLHS. RS should be looked for in this situation. It is important to mention that neuroimaging does not allow distinguishing between isolated RS and GLHS. If RS is diagnosed the clinical signs of GLHS should be sought. The diagnosis of GLHS can only be made by the combination of the typical dysmorphic signs and neuroimaging in the neonatal period, but not prenatally.

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.
