  Thereafter, she acquired abnormal behavior with hyperactivity, self-injury behaviors, and spells of crying, moaning, and stereotypical hand movements. [jmhg.springeropen.com]

  Children with Pitt-Hopkins syndrome also exhibit stereotypic hand movements, which include hand clapping, hand flapping, flicking hands, hand washing, fingers crossing, and frequent hand-to-mouth movements. [rarediseases.org]

  Other common findings are autism spectrum disorder symptoms, sleep disturbance, stereotypic hand movements, seizures, constipation, and severe myopia. [ncbi.nlm.nih.gov]

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

• Focal Epileptiform Discharges

  Focal epileptiform discharges were seen in 76%, 19% had generalized epileptiform discharges, and only one patient (4%) had a normal EEG without epileptiform discharges[3]. Attempts to evaluate genotype-phenotype correlations have been inconclusive. [jtggjournal.com]

• Generalized Epileptiform Discharges

  Focal epileptiform discharges were seen in 76%, 19% had generalized epileptiform discharges, and only one patient (4%) had a normal EEG without epileptiform discharges[3]. Attempts to evaluate genotype-phenotype correlations have been inconclusive. [jtggjournal.com]

• Gliosis

  For abnormal studies, findings were categorized as microcephaly, gliosis, myelination abnormalities, hypoplasia or atrophy, and dysplasia of the corpus callosum. EEGs were obtained for clinical indications. [jtggjournal.com]

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]

Larger studies are needed to confirm this observation, which may guide the prognosis and diagnosis of epilepsy in PTHS. PTHS patients have three types of paroxysmal events: epileptic seizures, abnormal breathing spells, and motor stereotypies. [jtggjournal.com]

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]

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]

Past 2-week symptoms of depression were assessed using the Center for Epidemiologic Studies Depression Scale [29,30]. The post-traumatic stress disorder (PTSD) Checklist Civilian Version was used to assess for past-month PTSD symptoms [31,32]. [journals.lww.com]

Epidemiology No population-based prevalence or incidence figures for PTHS are available at present. Until 2007, PTHS was rarely reported, but increasing numbers of patients have been published since molecular testing became available. [karger.com]
