Abstract Intellectual disability (ID) is a clinically and genetically heterogeneous disorder, affecting 1–3% of the general population. Although research into genetic causes ID has recently gained momentum, identification pathogenic mutations that cause autosomal recessive (ARID) lagged behind, predominantly due to non-availability sizeable families. Here we present results exome sequencing in 121 large consanguineous Pakistani In 60 families, identified homozygous or compound heterozygous...

Scientific data regarding effects of platelet transfusion on count in dengue-related thrombocytopenia is scanty.A single center, randomized non-blinded trial was conducted adult patients with dengue fever and counts less than 30,000/μl. Patients were to treatment control group. Treatment group received donor platelets. post-transfusion increment (PPI) ≥10,000/μl and/or corrected (CCI) ≥5,000/μl 1 h considered responders. Primary outcome increments at 24 72 h.87 enrolled, 43 (48.2%)...

Purpose: To identify the genetic origins of autosomal recessive congenital cataracts (arCC) in Pakistani population. Methods: Based on hypothesis that most arCC patients consanguineous families Punjab areas Pakistan should be homozygous for causative mutations, affected individuals were screened homozygosity nearby highly informative microsatellite markers and then pathogenic mutations by DNA sequencing. A total 83 unmapped 33 known candidate genes. Results: Patients 32 near at least 1 CC...

Human cortical development is a complex process involving the proliferation, differentiation, and migration of progenitor cells, all coordinated within dynamic extracellular matrix (ECM). ECM plays crucial role in guiding these processes, yet its specific contributions implications dysregulation neurodevelopmental disorders (NDDs) remain underexplored. In this study, we conducted meta-analysis single-cell RNA sequencing (scRNA-seq) data from 37 donors, gestational weeks (GWs) 8 to 26 across...

Although most symptomatic dengue infections follow an uncomplicated course, complications and unusual manifestations are increasingly being reported due to rising disease burden. Expanded syndrome is a new entity added into World Health Organization (WHO) classification system incorporate this wide spectrum of manifestations. We report case expanded with subacute thyroiditis intracerebral hemorrhage. This the first in infection. A 20 years old man presented fever, myalgias, arthralgias,...

To elucidate the novel molecular cause in two unrelated consanguineous families with autosomal recessive intellectual disability.A combination of homozygosity mapping and exome sequencing was used to locate plausible genetic defect family F162, while only followed PKMR65. The protein 3D structure visualized University California-San Francisco Chimera software.All five patients from both presented severe disability, aggressive behavior, speech motor delay. Four had microcephaly. We identified...
