Article Synopsis
- 46,XY gonadal dysgenesis (GD) is a disorder that leads to underdeveloped testes and results in ambiguous genitalia, often linked to genetic factors like duplications at the Xp21.2 locus affecting the NR0B1 (DAX1) gene.
- Recent findings indicate a complex genetic variant may also lead to GD without directly involving NR0B1, highlighting the complexity of this condition.
- The study presents three families with NR0B1 duplications found during prenatal screenings, including cases of phenotypically normal males, suggesting that the implications of these genetic variations are broader than previously understood and could help in prenatal genetic counseling.
Altered sensory functioning is often observed in individuals with SHANK3 related Phelan-McDermid syndrome (PMS). Compared to typically developing individuals and individuals with an autism spectrum disorder, it has been suggested that there are distinctive features of sensory functioning in PMS. More hyporeactivity symptoms and less hyperreactivity and sensory seeking behaviour are seen, particularly in the auditory domain.

Aim: To characterize the neurodevelopmental profile of patients with Phelan-McDermid syndrome (PMS) and describe the nature and trajectory of regression.
Method: This was a retrospective, monocentric study examining the clinical and developmental data of 24 patients (average age = 25 years 6 months, range = 6-56 years, n = 13 males) with a confirmed 22q13.3 terminal deletion carried out at the Centre for Human Genetics, University Hospital Leuven.
Article Synopsis
- Non-invasive prenatal testing can identify common trisomies (13, 18, 21) and also rare autosomal trisomies (RATs), which occur at about half the frequency of the common ones in large populations.
- There is a lack of extensive studies and clear clinical guidelines to help healthcare professionals and patients manage cases involving RATs effectively.
- This review consolidates knowledge on RATs, discussing their incidence, origins, related risks, and emphasizes the need for further research in this area for better prenatal management.
Article Synopsis
- Researchers have identified a connection between haploinsufficiency of the OTULIN gene and severe responses to staphylococcal infections in patients, leading to life-threatening necrosis.
- This condition is similar to the symptoms seen in Cri-du-Chat syndrome, which involves a deletion on chromosome 5p.
- The impairment from OTULIN causes an accumulation of linear ubiquitin in skin cells, leading to increased vulnerability to the staphylococcal toxin α-toxin, despite no changes in blood immune cells.
