As the pre-eminent global organization for families affected by the rare genetic condition Phelan-McDermid syndrome, the Foundation has positioned itself to play a leading role in patient advocacy and family support and driving research breakthroughs.
The objective of these updated clinical management guidelines was to: (1) reflect the latest in knowledge in PMS and (2) provide…
Early onset sleep problems and disorders are very common in individuals with Phelan-McDermid Syndrome (PMS) with rates of up to 90%. These sleep problems and disorders cannot be taken lightly. Not only do they have a major impact on the health, behaviour, functioning and learning opportunities of affected individuals, they can also have detrimental effects on the well-being and resilience of parents and caregivers, ultimately affecting the physical health, mental health and well-being of the whole social system.
The manifestations of Phelan-McDermid syndrome (PMS) are complex, warranting expert and multidisciplinary care in all life stages. In the present paper we propose consensus recommendations on the organization of care for individuals with PMS.
Phelan-McDermid syndrome is a rare genetic condition caused by a deletion encompassing the 22q13.3 region ora pathogenic variant of the gene SHANK3. The clinical presentation is variable, but main characteristics includeglobal developmental delay/intellectual disability (ID), marked speech impairment or delay, along with otherfeatures like hypotonia and somatic or psychiatric comorbidities.
Phelan-McDermid syndrome (PMS) is a neurodevelopmental disorder caused by deletions 22q13.3 or pathogenic variants in the SHANK3 gene. Lymphedema can be a clinical feature in 10-25% of individuals with PMS due to a deletion 22q13.3, but is not observed in those with a SHANK3 variant. This paper forms a part of the European consensus guideline for PMS and focuses on what is known regarding lymphedema in PMS in order to present clinical recommendations.
Gastrointestinal (GI) problems are common in Phelan-McDermid syndrome (PMS). Chewing and swallowing difficulties, dental problems, reflux disease, cyclic vomiting, constipation, incontinence, diarrhoea, and nutritional deficiencies have been most frequently reported.
Despite the inclusion of catatonia as a specifier of autism spectrum disorder in DSM-5, we—a team of child and adolescent neuropsychiatrists who specialise in paediatric catatonia and neurodevelopmental disorders—have identified a number of issues with the diagnosis and clinical management of catatonia in our patients.
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and restricted interests and behaviors which begin very early in life. In about a quarter of cases, the symptoms emerge about 18–24 months after a period of normal development, a phenomenon commonly described as early regression. However, marked functional decline can also occur in persons with autism after a relatively stable childhood.
This EL-PFDD meeting was modeled after the work of the FDA’s Patient Focused Drug Development (PFDD) initiative. PFDD is a systematic way of gathering patient perspectives on their condition and on available treatments. The information gathered at the meeting is presented in this Voice of the Patient report, a high-level summary of the perspectives generously shared by the families and caregivers of individuals living with PMS, who participated in the November 8, 2022, EL-PFDD meeting. The report also includes selected comments that were submitted through an online portal.
