Background: Rett syndrome is characterized by the loss of speech and purposeful hand movements, ambulation problems, and typical hand stereotypies. Preserved speech variant Rett syndrome (Zappella Variant) is a much less common form where speech is relatively preserved, from words to simple sentences. Lower urinary tract dysfunction and neurogenic bladder due to autonomic involvement have been only rarely reported in Rett syndrome. We aimed to emphasize neurogenic bladder due to autonomic dysfunction, which has very rarely been reported in the literature, in a patient with preserved speech variant Rett syndrome, a rare form of the Rett syndrome.
Case presentation: A 7-year-old female patient who had been diagnosed with severe vesicoureteral reflux and neurogenic bladder when 11 months old due to the inability to urinate was suspected of suffering from Rett syndrome after intense eye contact and the stereotypic movement of hand wringing were observed. The patient could talk with phrases and walk and had purposeful hand movements. The presence of the c.961C>T (p.Arg321Trp) mutation in the C terminal region of the MECP2 gene was demonstrated with Sanger sequencing. The patient is currently 13 years old and is receiving special education and continues to be monitored for chronic renal disease at the pediatric nephrology department.
Conclusion: The presence of hand stereotypies and intense eye pointing could indicate the Zappella variant Rett syndrome in a female patient who has developmental problems, can talk, has purposeful hand skills. Rett syndrome patients can also have lower urinary tract dysfunction although this is less common than cardiac, respiratory and gastrointestinal autonomic involvement. The development of intermittent urinary retention and vesicoureteral reflux may be associated with neurogenic bladder caused by autonomic involvement should be considered in these patients and one must be aware of the complications.

Giriş-Amaç: Rett sendromu, konuşma ve anlamlı el hareketlerinin kaybı, yürüme sorunları ve tipik el stereotipleri ile karakterizedir. Konuşmanın korunduğu varyantı Rett sendromu (Zappella Variant), kelimelerden basit cümlelere kadar konuşmanın nispeten korunduğu daha az yaygın bir formdur. Rett sendromunda alt üriner sistem disfonksiyonu ve otonomik tutuluma bağlı nörojenik mesane nadiren rapor edilmiştir. Rett sendromunun nadir görülen bir formu olan korunmuş konuşma varyantı Rett sendromu olan bir hastada, literatürde çok nadir bildirilen otonomik disfonksiyona bağlı nörojenik mesaneyi vurgulamayı amaçladık.
Vaka sunumu: İdrar yapamama nedeniyle 11 aylıkken şiddetli vezikoüreteral reflü ve nörojenik mesane tanısı konulan 7 yaşındaki kız hastanın, yoğun göz teması ve basmakalıp el ovuşturma hareketi sonrasında Rett sendromundan şüphelenildi. Hasta cümlelerle konuşabiliyor, yürüyebiliyor ve amaçlı el hareketleri yapabiliyordu. MECP2 geninin C terminal bölgesinde c.961C>T (p.Arg321Trp) mutasyonunun varlığı sanger dizilimi ile gösterildi. Hasta şu anda 13 yaşında özel eğitim almakta olup, çocuk nefrolojisi bölümünde kronik böbrek hastalığı açısından takip edilmeye devam etmektedir.
Sonuç: Gelişimsel sorunları olan, konuşabilen, amaçlı el becerilerine sahip bir kadın hastada sterotipik el hareketleri ve yoğun göz teması varlığı Zappella varyantı Rett sendromuna işaret edebilir. Rett sendromu hastalarında ayrıca alt üriner sistem disfonksiyonu da görülebilir, ancak bu durum kalp, solunum ve gastrointestinal otonomik tutulumdan daha az görülür. Bu hastalarda intermittan idrar retansiyonu ve vezikoüreteral reflü gelişiminin otonomik tutuluma bağlı nörojenik mesane ile ilişkili olabileceği göz önünde bulundurulmalı ve komplikasyonlara karşı dikkatli olunmalıdır.

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
