Genetic causes of primary immunodeficiency in the Jordanian population.

Ιnborn errors of immunity (IEI) represents a heterogenous collection of >480 immune system anomalies, leading to severe infections, autoimmune disorders and malignancies. While these conditions are rare globally, their prevalence is notably higher in the Jordanian population, attributed to elevated rates of consanguinity. The intricate nature of IEI has driven the adoption of genomic technologies for the identification of associated genetic defects.

Variant Analysis of Alkaptonuria Families with Significant Founder Effect in Jordan.

Background: Metabolic disorder alkaptonuria is an autosomal recessive disorder caused by mutations in the gene, and a deficiency HGD enzyme activity results in an accumulation of homogentisic acid (HGA), ochronosis, and destruction of connective tissue.

Methods: We clinically evaluated 18 alkaptonuria patients (age range, 3 to 60 years) from four unrelated families. Furthermore, 11 out of 18 alkaptonuria patients and 7 unaffected members were enrolled for molecular investigations by utilizing Sanger sequencing to identify variants of the 14 exons of gene.

Investigation of ACE rs4646994, MTHFR rs1801133 and VDR rs2228570 Genotypes in Jordanian Patients with Fibromyalgia Syndrome.

Background: Fibromyalgia syndrome (FMS) is a chronic disease characterized by widespread body pain, weakness in certain parts of the body (critical points), low pain tolerance, sleep disturbances, and fatigue. This syndrome is considered rare in Jordan.

Objectives: The research aimed to find out the association of the angiotensin converting enzyme, methylenetetrahydrofolate reductase, and vitamin D receptor (ACE, MHFTR, and VDR, respectively) genotypes with FMS among Jordanian patients.
