Background: DOORS syndrome (deafness, onychodystrophy, osteodystrophy, mental retardation and seizures; MIM 220500) is a rare multisystem genetic disorder, mainly characterized by sensorineural deafness, shortened terminal phalanges with small nails of hands and feet, intellectual deficit, and seizures. The disease is caused by homozygous or compound heterozygous mutation in the TBC1 domain family member 24 (TBC1D24) gene (gene locus/MIM 613577) on chromosome 16p13.
Objectives: We report the first case of DOORS syndrome from Indonesia.
Materials And Methods: A review of the literature was conducted and cases compared.
Results: A 27-day-old baby girl was brought to us with a history of recurrent seizures and absence of all finger- and toenails since birth. In addition, physical examination revealed left eye strabismus and a single transverse palmar crease on both hands. X-rays of the hands and feet showed absence of the distal phalanx of her right and left fingers II-V and the distal phalanx of her right and left toes I-V, respectively. Brainstem-evoked response audiometry test revealed profound bilateral sensorineural deafness. Pentalogy of Fallot was diagnosed by echocardiography, while an abnormal diffuse epileptiform pattern was found on electroencephalography.
Conclusion: This is the first report of an association between pentalogy of Fallot and single transverse palmar crease in DOORS syndrome.

The efficacy of Bone Marrow Mesenchymal Stem Cell-derived Exosomes (BMSCs-Exo) in addressing the complexities of Polycystic Ovary Syndrome (PCOS) has been explored in a controlled experimental study using a DHEA-induced PCOS model in 6-8-week-old female NMRI mice. This research undertook an in vivo approach with fifteen female murine subjects to investigate the potential of BMSCs-Exo in promoting vascular regeneration and alleviating the adverse effects associated with PCOS. Through a strategic intervention, the study aimed to modulate the pathophysiological markers of oxidative stress and inflammation that are hallmark features of PCOS.

The vacuolar H-ATPase (V-ATPase) is a functionally conserved multimeric complex localized at the membranes of many organelles where its proton-pumping action is required for proper lumen acidification. The V-ATPase complex is composed of several subunits, some of which have been linked to human disease. We and others previously reported pathogenic dominantly acting variants in ATP6V1B2, the gene encoding the V1B2 subunit, as underlying a clinically variable phenotypic spectrum including dominant deafness-onychodystrophy (DDOD) syndrome, Zimmermann-Laband syndrome (ZLS), and deafness, onychodystrophy, osteodystrophy, intellectual disability, and seizures (DOORS) syndrome.
