Genetic factors play an important role in type 2 diabetes (T2D) complications. Alteration of cerebrovascular blood flow (CBF) is a direct result of cerebrovascular diseases. However, few studies have reported the role of genetics on CBF in patients with T2D. We investigated whether single-nucleotide polymorphisms (SNPs) in metabolic disease genes are associated with CBF in patients with T2D. CB...

BACKGROUND AND OBJECTIVES MYH9-related disorders are autosomal dominant hereditary macrothrombocytopenias caused by mutations in the MYH9 gene. This gene encodes the non-muscular myosin heavy chain type II A (MHCIIA). Among these disorders, May-Hegglin anomaly (MHA), Sebastian syndrome (SS), and Fechtner syndrome (FS) are associated with different types of ribosome inclusions in granulocytes. F...

BACKGROUND Although MYH9 is strongly associated with biopsy-proven idiopathic and HIV-associated focal segmental glomerulosclerosis (FSGS) and clinically diagnosed 'hypertension-associated' end-stage renal disease (ESRD) in African Americans, its role in type 2 diabetes mellitus (T2DM)-associated ESRD is unclear. METHODS To assess whether MYH9 was associated with T2DM-ESRD, 751 African Americ...

BACKGROUND African Americans (AA) disproportionately develop lupus nephritis (LN) relative to European Americans and familial clustering supports causative genes. Since MYH9 underlies approximately 40% of end-stage renal disease (ESRD) in AA, we tested for genetic association with LN. METHODS Seven MYH9 single nucleotide polymorphisms (SNPs) and the E1 risk haplotype were tested for associati...

The MYH9 gene encodes a protein that is expressed in the kidney glomerular podocytes. MYH9 single nucleotide polymorphisms (SNPs) have been linked to the risk for chronic kidney disease (CKD) and end stage renal disease. Our aim was to determine whether MYH9 SNPs were associated with renal disease in Spanish Caucasians. The RENASTUR cohort consisted of 592 Spanish Caucasians, aged 55-85 years. ...

MYH9-related disease (MYH9-RD) is a rare genetic syndromic disorder characterised by congenital thrombocytopenia and is associated with the risk of developing progressive sensorineural hearing loss, nephropathy and presenile cataracts during childhood or adult life. All consecutive patients enrolled in the Italian Registry for MYH9-RD with severe to profound deafness were included in a retrospe...

Study Hypothesis African Americans have much higher rates of kidney failure than those of European ancestry. Previous genetic studies found variation at or near the MYH9 gene to be associated with increased risk of focal segmental glomerulosclerosis (FSGS) and hypertension-attributed end-stage kidney disease (H-ESKD), but the causal mutations in MYH9 were not identified. The authors hypothesize...

Myosin heavy chain-9-related disorders (MYH9-RDs) are a group of autosomal-dominant disorders caused by mutations in the MYH9 gene. The features include congenital macrothrombocytopaenia, inclusion bodies in neutrophils and a variable risk of developing sensorineural deafness, progressive renal impairment and presenile cataracts. A 44-year-old Caucasian man was initially thought to have Alport'...

Megakaryocyte ploidy and the generation of pre/proplatelets are both increased in culture by pharmacologic inhibition of myosin-II, but nonmuscle myosin-IIA (MIIA) mutations paradoxically cause MYH9-related diseases (MYH9-RD) that adversely affect platelets. In marrow, megakaryocytes extend projections into the microcirculation, where shear facilitates fragmentation to large pre/proplatelets, s...

Single nucleotide polymorphisms (SNPs) in MYH9 and APOL1 on chromosome 22 (c22) are powerfully associated with non-diabetic end-stage renal disease (ESRD) in African Americans (AAs). Many AAs diagnosed with type 2 diabetic nephropathy (T2DN) have non-diabetic kidney disease, potentially masking detection of DN genes. Therefore, genome-wide association analyses were performed using the Affymetri...
