During the past ten years a particular molecular technology - array comparative genomic hybridization (aCGH)--has received a great deal of attention. Array CGH can detect simultaneously sub-microscopic copy number changes across the whole genome, thus overcoming the limitations of karyotyping or locus-specific techniques. Array CGH has become an important(More)
The last years modified major our conceptions about nutrition. These revolutionary changes were produced by implementation of new techniques of functional genomics. The nutrigenomics and nutrigenomics provide powerful approaches to unravel the complex relationships between bioactive molecules, genetic polymorphisms and biological system and can give rise to(More)
UNLABELLED Patau syndrome has an incidence of 1/10.000-20.000, the clinical diagnosis being suggested by the triad cleft lip and palate, microphthalmia/anophthalmia and postaxial polydactyly. Most frequent cytogenetic abnormality is free and homogeneous trisomy 13 (80.0%), rarely being detected trisomy mosaics or Robertsonian translocations. The objective(More)
The infertility is a important health problem, affecting about 10-15% of couples. The important role of genetic factors in pathogenesis of infertility is now increasingly recognized and our knowledges in this field are improved each day. For these reasons we review the most important genetic causes of infertility. In this paper we analyse the genetic(More)
Ring chromosomes are rare entities, usually associated with phenotypic abnormalities in correlation with the loss of genetic material. There are various breakpoints and sometimes there is a dynamic mosaicism that is reflected in clinical features. Most of the ring chromosomes are de novo occurrences. Our study reflects the experience of three Romanian(More)
UNLABELLED Velo-Cardio-Facial Syndrome (VCFS) is characterized by congenital heart defects (CHD), palatal abnormalities, facial dysmorphism, neonatal hypocalcemia, immune deficit, speech and learning disabilities. SVCF is caused by microdeletion 22q11.2. Microdeletion is detected by fluorescence in situ hybridization (FISH). The highly variable phenotype(More)
We present a retrospective study aimed to identify the correlation between de Vries clinical score and the detection of chromosomal abnormalities in mentally retarded (MR) children. We have used the score to identify patients who should be tested by karyotyping and subsequently MLPA (multiplex ligation dependent probe amplification) for subtelomeric(More)
Neurodegenerative diseases, such as Alzheimer's dementia, Huntington's chorea, Parkinson's disease or spinocerebellar ataxia, manifests into adulthood with an insidious onset, slowly of progressive symptoms. All of these diseases are characterized by presimptomatic stages that preceded with many years of clinical debut. In Parkinson's disease, more than(More)

UNLABELLED Prenatal diagnosis (PD) by FISH or cell culture is today an important tool for the prevention of chromosomal anomalies. A difficult issue is prenatal detection of gonosomal anomalies. Most gonosomal anomalies neither affect life expectancy nor cause psychomotor retardation, but sexualization disorders and the lack of reproductive potential are a(More)
