Expanding the neurodevelopmental phenotype of PURA syndrome.

PURA syndrome is a recently described developmental encephalopathy presenting with neonatal hypotonia, feeding difficulties, global developmental delay, severe intellectual disability, and frequent apnea and epilepsy. We describe 18 new individuals with heterozygous sequence variations in PURA. A neuromotor disorder starting with neonatal hyptonia, but ultimately allowing delayed progression to walking, was present in nearly all individuals. Congenital apnea was present in 56% during infancy, but all cases in this cohort resolved during the first year of life. Feeding difficulties were frequently reported, with gastrostomy tube placement required in 28%. Epilepsy was present in 50% of the subjects, including infantile spasms and Lennox-Gastaut syndrome. Skeletal complications were found in 39%. Disorders of gastrointestinal motility and nystagmus were also recurrent features. Autism was diagnosed in one individual, potentially expanding the neurodevelopmental phenotype associated with this syndrome. However, we did not find additional PURA sequence variations in a cohort of 120 subjects with autism. We also present the first neuropathologic studies of PURA syndrome, and describe chronic inflammatory changes around the arterioles within the deep white matter. We did not find significant correlations between mutational class and severity, nor between location of the sequence variation in PUR repeat domains. Further studies are required in larger cohorts of subjects with PURA syndrome to clarify these genotype-phenotype associations.

Identifying Components of Autism Friendly Health Care: An Exploratory Study Using a Modified Delphi Method.

OBJECTIVES: Autistic individuals report lower health care satisfaction. However, there is currently no set of "best practice" standards about caring for autistic individuals. In this exploratory study, we aim to identify features of Autism Friendly practice according to a sample consisting of mainly professionals whose interests include autism using a modified 3-round Delphi-a method that identifies a consensus view across subject participants. METHODS: Statements about components of an Autism Friendly health care practice were compiled in consultation with the steering committee of an Autism Friendly Initiative at a single, urban academic safety-net hospital. Participants were recruited through our national network of professionals and patients/families mailing list. Examples of invited professionals included researchers, health care workers, and educators. In the first 2 rounds, we distributed electronic surveys to participants, who scored statements from 1 to 9 regarding importance. In round 2, statements that were scored low by all stakeholder groups were eliminated. Seventy-eight participants responded to the first-round survey, and 51 participants responded to the second-round survey. In the third round, 38 participants ranked 16 statements from most to least important. Statements are summarized and presented in the Results section. RESULTS: Topics that emerged from highly ranked statements include environmental/operational modifications (e.g., longer appointment times) and staff training to support autistic patients. CONCLUSION: Highly ranked statements represented previously reported barriers, including the need for staff training and inclusive engagement with the autistic community. The findings can help inform health care organizations to determine priorities when building an Autism Friendly health care practice.
