BACKGROUND The activated protein C (APC) resistance is the most common prothrombotic defect in thrombosis patients, mainly related with alterations in the F5 gene. In this work, we evaluated the presence of variants in the FV gene in Amerindian patients with deep venous thrombosis and APC resistance. METHODS A total of 87 patients with deep venous thrombosis (DVT) confirmed by Doppler ultraso...
A Comprehensive In Silico Analysis of the Functional and Structural Impact of SNPs in the IGF1R Gene
Insulin-like growth factor 1 receptor (IGF1R) acts as a critical mediator of cell proliferation and survival. Many single nucleotide polymorphisms (SNPs) found in the IGF1R gene have been associated with various diseases, including both breast and prostate cancer. The genetics of these diseases could be better understood by knowing the functions of these SNPs. In this study, we performed a comp...
The aim of this study was to screen the visual system homeobox 1 (VSX1) gene in Turkish patients with keratoconus (KC). The patient group consisted of 44 patients who had undergone corneal transplant surgery before the age of 30, for advanced and rapidly progressive KC. The control group comprised 250 healthy individuals. We detected two missense mutations, D144N and D295Y, in exon 2 and exon 5...
The aim of this study was to identify the mutation site and phenotype of the Duchenne muscular dystrophy (DMD) gene in a DMD family. The DMD gene is by far the largest known gene in humans. Up to 34% of the point mutations reported to date affect splice sites of the DMD gene. However, no hotspot mutation has been reported. Capture sequencing of second-generation exons was used to investigate th...
BACKGROUND Mucopolysaccharidosis type I (MPS I) is an autosomal recessive disease due to deficiency of α-L-iduronidase (IDUA), a lysosomal enzyme that degrades glycosaminoglycans (GAG) heparan and dermatan sulfate. To achieve optimal clinical outcomes, early and proper treatment is essential, which requires early diagnosis and phenotype severity prediction. RESULTS To establish a genotype/phe...
MOTIVATION Single nucleotide polymorphisms (SNPs) analysis is an important means to study genetic variation. A fast and cost-efficient approach to identify large numbers of novel candidates is the SNP mining of large scale sequencing projects. The increasing availability of sequence trace data in public repositories makes it feasible to evaluate SNP predictions on the DNA chromatogram level. MA...
background: premature ovarian failure (pof) is an ovarian defect characterized by the premature depletion of ovarian follicles before the age of 40, representing one major cause of female infertility. mutations in bone morphogenetic protein 15 (bmp15) and growth differentiation factor 9 (gdf9) have been shown to be associated with pof. methods: genomic dna was isolated from 52 idiopathic premat...
PURPOSE Microphthalmia, anophthalmia, and coloboma are ocular malformations with a significant genetic component. Rx is a homeobox gene expressed early in the developing retina and is important in retinal cell fate specification as well as stem cell proliferation. We screened a group of 24 patients with microphthalmia, coloboma, and/or anophthalmia for RX mutations. METHODS We used standard P...
Single nucleotide polymorphisms (SNPs) are the most common source of genetic variation in populations and are thus most likely to account for the majority of phenotypic and behavioral differences between individuals or strains. Although the rat is extensively studied for the latter, data on naturally occurring polymorphisms are mostly lacking. We have used publicly available sequences consistin...
The BRCA1 tumor suppressor gene is found mutated in familial breast cancer. Although many of the mutations are clearly pathological because they give rise to truncated proteins, several missense variants of uncertain pathological consequences have been identified. A novel functional assay to screen for BRCA1 missense variants in a simple genetic system could be very useful for the identificatio...
