We examined the effect of vitamin D receptor (VDR) polymorphisms at exon 2 (FokI) and intron 8 (BsmI) on the stature and bone mineral density at femoral neck (FBMD) and lumbar spine (LBMD) in 108 prepubertal and pubertal homozygous beta thalassaemic patients, regularly treated. We found significantly shorter stature and lower LBMD and FBMD in all patients with CC VDR genotype, and significant shorter height and lower LBMD in prepubertal and pubertal female patients with BB VDR genotype. Because homozygous CC and BB VDR genotypes influence Vitamin D activity, they can be considered additional risk factors for bone disease in beta thalassaemia.

Introduction/objectives: Psoriatic arthritis (PsA) is a chronic inflammatory rheumatic disease strongly associated with psoriasis. We hypothesized that the presence of variant alleles in VDR may be associated with worse clinical outcomes. The aim of this study was to evaluate a possible association between the FokI and TaqI polymorphisms in the VDR gene and clinical markers of disease activity and functional status in PsA.

Background: Tuberculosis (TB) treatment relies on a prolonged first-line antibiotic regimen, including isoniazid, rifampicin (RF), ethambutol (EMB), and pyrazinamide.Pharmacogenetics plays a crucial role in optimizing TB treatment by addressing individual variability in drug metabolism and responses. Genetic polymorphisms can significantly affect pharmacokinetics and therapeutic outcomes.

Atopic dermatitis (AD), a common chronic inflammatory disease in children and adults, is often studied to find the best way to prevent or reduce its severity. One of the substances tested so far is vitamin D. The main aim of this paper was to determine whether vitamin D truly brings benefits to people with AD or whether its action is too insignificant to have clinical significance.

Background: Hypovitaminosis D has been associated with worse rheumatoid arthritis (RA) manifestations. Notably, different genetic studies have reported that approximately 65% of hypovitaminosis D can be partially explained using the presence of single-nucleotide variants (SNVs) in key genes involved in its metabolism. This study aimed to investigate the association and gene-gene interactions of four SNVs in vitamin D metabolism genes, rs10741657 (), rs10877012 (), rs4809959 ), and rs731236 () with hypovitaminosis D, RA, and its clinical disease activity in a Mexican mestizo population.

The genetic background influences the outcomes of COVID-19. This study aimed to evaluate the incidence of polymorphisms in genes linked to the RAAS system, cytokine production, and vitamin D on COVID-19 severity, with the goal of gaining a deeper understanding of the genetic etiology related to COVID-19. This study involved 338 COVID-19 patients and employed machine learning methods to identify the genetic variants that most significantly affect COVID-19 severity.
