Expanding the Phenotypic Spectrum of TRAF7-Related Cardiac, Facial, and Digital Anomalies With Developmental Delay: Report of 11 New Cases and Literature Review.

Background: TRAF7-related cardiac, facial, and digital anomalies with developmental delay (CAFDADD), a multisystemic neurodevelopmental disorder caused by germline missense variants in the TRAF7 gene, exhibits heterogeneous clinical presentations.

Methods: We present a detailed description of 11 new TRAF7-related CAFDADD cases, featuring eight distinct variants, including a novel one.

Results: Phenotypic analysis and a comprehensive review of the 58 previously reported cases outline consistent clinical presentations, emphasizing dysmorphic features, developmental delay, endocrine manifestations, and cardiac defects.

Snijders Blok-Campeau Syndrome: Description of 20 Additional Individuals with Variants in and Literature Review.

Snijders Blok-Campeau syndrome (SNIBCPS, OMIM# 618205) is an extremely infrequent disease with only approximately 60 cases reported so far. SNIBCPS belongs to the group of neurodevelopmental disorders (NDDs). Clinical features of patients with SNIBCPS include global developmental delay, intellectual disability, speech and language difficulties and behavioral disorders like autism spectrum disorder.

Genotypic Findings in Noonan and Non-Noonan RASopathies and Patient Eligibility for Growth Hormone Treatment.

Molecular study has become an invaluable tool in the field of RASopathies. Treatment with recombinant human growth hormone is approved in Noonan syndrome but not in the other RASopathies. The aim of this study was to learn about the molecular base of a large cohort of patients with RASopathies, with particular emphasis on patients with pathogenic variants in genes other than , and its potential impact on rGH treatment indication.

Variability in Phelan-McDermid Syndrome in a Cohort of 210 Individuals.

Phelan-McDermid syndrome (PMS, OMIM# 606232) results from either different rearrangements at the distal region of the long arm of chromosome 22 (22q13.3) or pathogenic sequence variants in the gene. codes for a structural protein that plays a central role in the formation of the postsynaptic terminals and the maintenance of synaptic structures.

Novel biallelic variant in BBS9 causative of Bardet-Biedl syndrome: expanding the spectrum of disease-causing genetic alterations.

Background: Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy disorder. Many BBS disease-causing genetic variants have been identified due to the advancement of molecular diagnostic tools. We report on a novel pathogenic variant in a consanguineous Pakistani family with an affected child.

Growth, development, and phenotypic spectrum of individuals with deletions of 2q33.1 involving SATB2.

SATB2-Associated syndrome (SAS) is an autosomal dominant, multisystemic, neurodevelopmental disorder due to alterations in SATB2 at 2q33.1. A limited number of individuals with 2q33.

New insights into genetic variant spectrum and genotype-phenotype correlations of Rubinstein-Taybi syndrome in 39 CREBBP-positive patients.

Background: Rubinstein-Taybi syndrome (RSTS) is a rare congenital disorder characterized by broad thumbs and halluces, intellectual disability, distinctive facial features, and growth retardation. Clinical manifestations of RSTS are varied and overlap with other syndromes' phenotype, which makes clinical diagnosis challenging. CREBBP is the major causative gene (55%-60% of the cases), whereas pathogenic variants found in EP300 represent the molecular cause in 8% of RSTS patients.

Rubinstein-Taybi 2 associated to novel EP300 mutations: deepening the clinical and genetic spectrum.

Background: Rubinstein-Taybi syndrome (RSTS) is a rare autosomal dominant neurodevelopmental disorder characterized by broad thumbs and halluces. RSTS is caused by mutations in CREBBP and in EP300 genes in 50-60% and 8%, respectively. Up to now, 76 RSTS-EP300 patients have been described.

First case report of inherited Rubinstein-Taybi syndrome associated with a novel EP300 variant.

Background: Rubinstein-Taybi syndrome (RSTS; OMIM #180849, #613684) is a rare autosomal dominant genetic condition characterized by broad thumbs and halluces, facial dysmorphism, short stature and variable degree of intellectual disability. RSTS is associated with mutations in CREBBP and EP300 genes in 50-60% and 5-8% of cases, respectively. The majority of cases are de novo heterozygous mutations.

DNA methylation profiling at imprinted loci after periconceptional micronutrient supplementation in humans: results of a pilot randomized controlled trial.

Intrauterine exposures mediated by maternal diet may affect risk of cardiovascular disease, obesity, and type 2 diabetes. Recent evidence, primarily from animal studies and observational data in humans, suggests that the epigenome can be altered by maternal diet during the periconceptional period and that these programming events may underlie later disease risk. A randomized controlled trial of periconceptional micronutrient supplementation in The Gambia, where seasonal nutritional variations affect fetal growth and postnatal outcomes, provided a unique opportunity to test this hypothesis.

Areca-nut abuse and neonatal withdrawal syndrome.

Areca-nut chewing occurs widely in South Asia and the Indian subcontinent. Here we present a case of neonatal withdrawal syndrome in an infant born to a woman who was a chronic areca-nut user. Arecoline, the principal neuroactive alkaloid in areca nuts, was found in the mother's placenta.

Acanthosis nigricans as an adverse effect of highly active antiretroviral therapy in an adolescent girl with human immunodeficiency virus infection.

We report an 11-year-old girl with acanthosis nigricans that appeared after 4 years of treatment with didanosine, stavudine and amprenavir. Laboratory studies showed hyperglycemia, hyperinsulinemia and hypertriglyceridemia. Withdrawal of amprenavir resulted in disappearance of acanthosis nigricans and improvement of metabolic abnormalities.
