Abstract

Background: Lujan–Fryns syndrome (LFS) is an extremely rare, X-linked disorder, for which the full clinical spectrum is still unknown. Usually, it presents with neuropsychiatric problems such as learning disabilities and behavioral issues in a typical combination with marfanoid features. Often, there is a positive family history for the disorder. However, sporadic cases have also been reported in males. More interestingly, there is no case of LFS presenting with acute-onset dysphagia in the English language medical literature.

Case presentation: A 17-year-old Pakistani mentally normal school boy was admitted for the workup of acute-onset dysphagia, hypernasal speech, and nasal regurgitation of liquids. He had no neuropsychiatric issues, and his family history was unremarkable. An obvious nasal twang, facial dysmorphism, and marfanoid body habitus were found on examination. The genetic tests revealed a pathogenic missense mutation in the MED12 gene on his X-chromosome.

Conclusion: LFS can present as acute-onset dysphagia and in the absence of any neuropsychiatric issues or positive family history of the syndrome.
