Succinate-CoA ligase (SUCL) is a heterodimer enzyme composed of Suclg1 α-subunit and a substrate-specific Sucla2 or Suclg2 β-subunit yielding ATP or GTP, respectively. In humans, the deficiency of this enzyme leads to encephalomyopathy with or without methylmalonyl aciduria, in addition to resulting in mitochondrial DNA depletion. We generated mice lacking either one Sucla2 or Suclg2 allele. Su...
The Candida albicans NOT4 gene was disrupted in order to investigate the role of Not4p in growth, morphogenesis and pathogenicity. Heterozygote (NOT4/not4), null (not4/not4) and reconstructed heterozygote ([NOT4]/not4) strains of C. albicans, as well as CAF2-1, the parental strain, were grown under conditions that promote hyphal formation. When cultured in liquid medium 199 the heterozygote, re...
Lymph chylomicrons radiolabelled in triacylglycerol and cholesteryl ester were injected into control and Watanabe heritable-hyperlipidaemic (WHHL) rabbits. Clearance of chylomicrons was slower in heterozygote and homozygote WHHL rabbits. Slower remnant clearance in WHHL rabbits was confirmed by monitoring the clearance from plasma of preformed chylomicron remnants. Use of chylomicron-like lipid...
Hereditary hemochromatosis has an autosomal recessive inheritance pattern. The homozygous diseased state occurs in 50 of 10,000 and the heterozygous non-diseased carrier state in 1000 of 10,000 caucasians.3 The typical case has two unaffected heterozygote carrier parents. However, HH can occur in consecutive generations owing to the chance mating between an as-yet-undetected homozygote and a he...
Hb E-Saskatoon and Hb G-Coushatta are rare hemoglobin variants that are not a health problem. Herein we present a Turkish woman that was diagnosed as homozygous Hb E-Saskatoon (only the second such case reported from Turkey) and a Turkish boy diagnosed as heterozygote Hb E-Saskatoon. Additionally, 2 Turkish sisters diagnosed as heterozygote Hb G-Coushatta are presented.
OBJECTIVES The aim of the study is to assess clinical characteristics of individuals with nonsyndromic sensorineural hearing loss (NSSNHL) with genetic mutations in GJB2 and/or GJB6. We describe and compare one group with biallelic mutations against a group of heterozygote mutation carriers. METHODS A total of 350 patients between the ages of 3 months and 80 years referred to a tertiary care ...
Explaining how polymorphism is maintained in the face of selection remains a puzzle since selection tends to erode genetic variation. Provided an infinitely large unsubdivided population and no frequency-dependance of selective values, heterozygote advantage is the text book explanation for the maintenance of polymorphism when selection acts at a diallelic locus. Here, we investigate whether th...
