Symptoma

Pitt-Hopkins-Like Syndrome Type 2

PTHSL2

In contrast to patients with Pitt-Hopkins syndrome, PTHSL2 patients present with normal or only mildly to moderately delayed motor milestones. [uniprot.org]

As this syndrome presents with severe hypotonia and feeding difficulties, it could be misdiagnosed as Angelman Syndrome and vice-versa. [cureangelman.org.au]

Although presentation varies a fair amount between individuals, all mutations appear to be equivalent, i.e. there is no obvious genotype-phenotype correlation. [cureffi.org]

At present to date Zach hasn't presented with these medical issues but this can not be guaranteed as he gets older. Since 10 months of age, Zach has been in weekly Physiotherapy sessions, Speech and OT. [chuffed.org]

  • Swelling

    They often have redness and swelling of the skin at the base of their nails and can have blunting of the normal angle at the baes of the nail (clubbing). They often have overriding toes. [rarediseases.org]

  • Failure to Thrive

    Other signals picked up as first signs by parents were failure to thrive, gastrointestinal problems (such as reflux, feeding problems, vomiting, constipation), and other symptoms, such as cyanosis during crying, breathing problems, seizures and abnormal [ojrd.biomedcentral.com]

  • Cyanosis

    They are characterized by fits of hyperventilation, often followed by apnea and cyanosis. Etiology The syndrome is caused by heterozygous de novo mutations in the TCF4 gene (18q21), coding for a ubiquitous b-HLH transcription factor. [orpha.net]

    These episodes can cause a lack of oxygen in the blood, leading to a bluish appearance of the skin or lips (cyanosis). In some cases, the lack of oxygen can cause loss of consciousness. [ghr.nlm.nih.gov]

    Hyperventilation may occur and is sometimes followed by apnea and cyanosis. Constipation is common. Microcephaly and seizures may occur. Hypopigmented skin macules have occasionally been reported. [en.wikipedia.org]

  • High Nasal Root

    Researchers have developed cell and rodent models to test therapies for Pitt Hopkins. [3] Signs and symptoms [ edit ] PTHS can be seen as early as childhood. [4] The earliest signs in infants is the lower face and the high nasal root. [5] The facial features [en.wikipedia.org]

  • Beak Nose

    Facial dysmorphism include a beaked nose, flared nostrils, and a wide mouth with a 'cupid's-bow' shaped upper lip. A particular breathing pattern is characteristic of PHS. [genome.jp]

Clinical Evaluations and Workup If the diagnosis is suspected by exam and history, molecular testing can be ordered. [rarediseases.org]

Treatments & Therapies Currently there is no known cure for Pitt Hopkins Syndrome and treatment is symptomatic. Affected persons often benefit from glasses and assistive communication devices. [pediatricbrainfoundation.org]

Pitt-Hopkins Syndrome Treatment Until now, doctors have only been able to treat the symptomatic problems of the patient. In fact, there is no pharmacological treatment to treat the cognitive and behavioral problems in these children. [blog.cognifit.com]

Prognosis The course of the disease is non-progressive. The documents contained in this web site are presented for information purposes only. [orpha.net]

Parents should talk to their children’s physician and medical team about their specific case, associated symptoms and overall prognosis. Infants with Pitt-Hopkins syndrome may have diminished muscle tone (hypotonia) and appear abnormally “floppy.” [rarediseases.org]

Sensory integration, speech, and behavioural therapies can help increase the quality of life for an affected individual. (8) Prognosis Most treatment strategies for the genetic disorders do not alter the underlying genetic mutation. [syndromespedia.com]

Because loss of TCF4 prevents neurons from functioning currently, our scientist believe that studying Pitt Hopkins will also give us important insight into other neurological disorders with no known etiology like Alzheimers, Autism and Epilepsy. o Facebook [milliondollarbikeride.org]

Etiology The syndrome is caused by heterozygous de novo mutations in the TCF4 gene (18q21), coding for a ubiquitous b-HLH transcription factor. [orpha.net]

Codes: ICD-10: Q87.0 ORPHA: 2896 Estimated occurrence 2-3:100,000 live births Etiology Pitt-Hopkins syndrome (PTHS) occurs due to a de novo mutation on gene TCF4, which is on chromosome 18q21.1. [mun-h-center.se]

Stephen Haggarty at Harvard has created the largest repository of Pitt Hopkins tissue samples to expand our understanding of the biology and pathophysiology of Pitt Hopkins Syndrome. [pitthopkinscare.org]

Aim of the project Mutations in a specific gene, Neurexin 1 (NRXN1), have been implicated in the pathophysiology of autism and other neuropsychiatric conditions. [autismresearchtrust.org]
