Haploinsufficiency of TCF4 causes syndromal mental retardation with intermittent hyperventilation (Pitt-Hopkins syndrome).
Pitt-Hopkins syndrome is a rarely reported syndrome of so-far-unknown etiology characterized by mental retardation, wide mouth, and intermittent hyperventilation. By molecular karyotyping with GeneChip Human Mapping 100K SNP arrays, we detected a 1.2-Mb deletion on 18q21.2 in one patient. Sequencing of the TCF4 transcription factor gene, which is contained in the deletion region, in 30 patients...
متن کاملPhenotype and natural history in 101 individuals with Pitt-Hopkins syndrome through an internet questionnaire system.
BACKGROUND Pitt-Hopkins syndrome (PTHS; MIM# 610954) is a genetically determined entity mainly caused by mutations in TransCription Factor 4 (TCF4). We have developed a new way to collect information on (ultra-)rare disorders through a web-based database which we call 'waihonapedia' (waihona [meaning treasure in Hawaiian] encyclopaedia). METHODS We have built a waihonapedia system in a collab...
متن کاملA case of Pitt-Hopkins syndrome presented with Angelman-like syndromic phenotypes

Its diverse clinical appearance causes pediatricians to confuse it with Angelman syndrome, which is considered one of the family members of Angelman-like syndrome. Herein, we report o...
متن کاملOsteopathic Manipulative Treatment Limits Chronic Constipation in a Child with Pitt-Hopkins Syndrome
Pitt-Hopkins Syndrome (PTHS) is a rare genetic disorder caused by insufficient expression of the TCF4 gene. Children with PTHS typically present with gastrointestinal disorders and early severe chronic constipation is frequently found (75%). Here we describe the case of a PTHS male 10-year-old patient with chronic constipation in whom Osteopathic Manipulative Treatment (OMT) resulted in improve...
متن کاملPitt-Hopkins syndrome: report of a case with a TCF4 gene mutation
AIMS We will discuss the clinical and genetic diagnosis of a child with severe psychomotor delay, who at 3 years of age presented with paroxysms of hyperpnea-apnea and seizures unrelated to breathing anomalies. METHODS The child underwent genetic (karyotype, FISH telomeres) and neuroradiological (cranial CT and MRI) tests, which proved to be normal. He came under our clinical observation at 3...
