Background: The diagnosis of PTEN hamartoma tumor syndrome (PHTS) is difficult in children because they usually do not meet diagnostic criteria. The objective of our study was to characterize lipoma as an early presentation of PHTS.

Methods: We performed a retrospective review of children with PHTS diagnosed in French academic hospitals from 2000 to 2019. We included patients presenting at least one lipoma and PTEN-related disorder confirmed genetically.

Results: Thirteen children were included (mean age 5.5 years [range 2.5-16]). All children had solitary (n = 5) or multiple (n = 8) lipomas, all located on the trunk. Clinical examination revealed macrocephaly in all patients. Genital lentiginosis was found in all patients in whom genitalia were examined (n = 6).

Conclusions: In addition to the classical presentation of PHTS with neurological disorders and macrocephaly, some patients, especially the youngest ones, have an initial dermatologic presentation with multiple lipomas. Search for penile freckling and macrocephaly in these patients allows for the diagnosis of PHTS. Lipomatosis should be a major diagnostic criterion in children.

Article Synopsis
  • Loss-of-function mutations in the CHD8 gene are linked to Autism Spectrum Disorders (ASD), leading to significant molecular and cellular changes relevant for developing new therapies.
  • Synthetic SINEUP-CHD8, a type of long non-coding RNA, can increase the production of the CHD8 protein in cells lacking it, and reverse associated negative effects in cells from patients with CHD8 mutations.
  • In zebrafish models, SINEUP-CHD8 not only alleviated symptoms caused by CHD8 suppression, like macrocephaly and excessive neuron production, but also suggests potential for RNA-based treatments for various neurodevelopmental disorders.

Article Synopsis
  • The TAOK proteins are important kinases involved in various cellular functions and are linked to neurodevelopmental disorders (NDDs) like those caused by TAOK1 and TAOK2 variants.
  • A study analyzed clinical and genetic data from individuals with these variants, revealing that TAOK1 variants lead to significant neurodevelopmental issues and some novel characteristics, while TAOK2 variants are tied to neurodevelopmental abnormalities, autism, and obesity.
  • This research expands the understanding of these disorders by presenting the largest cohort of individuals with TAOK1-NDD and identifying new variants and phenotypes associated with both TAOK1 and TAOK2.

A 10-month-old female infant, who was second-born, was referred for progressive macrocephaly, axial hypotonia, developmental delay, and limb stiffness. Birth had occurred at 41 weeks, after an uneventful pregnancy and delivery, to nonconsanguineous parents. Noticeably, the child could not hold her head up at 4 months or sit at 10 months of age.

The Chromodomain Helicase DNA-binding (CHD) protein family is ATP-dependent chromatin remodeling proteins that utilize energy produced by ATP hydrolysis to regulate chromatin structure and thereby modulate gene expression. The earliest report of a CHD3 gene mutation was by O'Roak, who found it during whole exome sequencing of 189 autism families in 2012. In 2018, Snijders Blok systematically assessed the autosomal dominant neurodevelopmental disorder caused by CHD3 gene damage, known as Snijders Blok-Campeau syndrome (SNIBCPS, OMIM 618205).

The X-linked NONO gene encodes Non-Pou Domain-Containing Octamer-Binding Protein, a multifunctional member of the DBHS family involved in transcriptional regulation, RNA splicing and DNA repair. Pathogenic variants in NONO cause Intellectual Developmental Disorder, X-linked Syndromic (MIM #300967), characterised by intellectual disability, neurodevelopmental delay, cardiomyopathy, such as left ventricular non-compaction (LVNC), and congenital heart defects such as including atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA), and patent foramen ovale (PFO). This study reports three new patients with pathogenic hemizygous frameshift variants in NONO identified with exome sequencing, broadening the clinical presentation.
