  2. 13q deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/13q_deletion_syndrome

    13q deletion syndrome is a rare genetic disease caused by the deletion of some or all of the large arm of human chromosome 13. Depending upon the size and location of the deletion on chromosome 13, the physical and mental manifestations will vary. It has the potential to cause intellectual disability and congenital malformations that affect a ...

  3. Chromosome 13 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_13

    Extra material from chromosome 13 disrupts the course of normal development, causing the characteristic signs and symptoms of trisomy 13. Researchers are not yet certain how this extra genetic material leads to the features of the disorder, which include severely abnormal cerebral functions, a small cranium, retardation, non functional eyes and ...

  4. Patau syndrome - Wikipedia

    en.wikipedia.org/wiki/Patau_syndrome

    Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13.The extra genetic material disrupts normal development, causing multiple and complex organ defects.

  5. Genetic algorithm - Wikipedia

    en.wikipedia.org/wiki/Genetic_algorithm

    Certain selection methods rate the fitness of each solution and preferentially select the best solutions. Other methods rate only a random sample of the population, as the former process may be very time-consuming. The fitness function is defined over the genetic representation and measures the quality of the represented solution. The fitness ...

  6. Chromosome conformation capture - Wikipedia

    en.wikipedia.org/wiki/Chromosome_conformation...

    Chromosome conformation capture-on-chip (4C) (also known as circular chromosome conformation capture) captures interactions between one locus and all other genomic loci. It involves a second ligation step, to create self-circularized DNA fragments, which are used to perform inverse PCR. Inverse PCR allows the known sequence to be used to ...

  7. CDK13-related disorder - Wikipedia

    en.wikipedia.org/wiki/CDK13-related_disorder

    CDK13-related disorder, also known as congenital heart defects, dysmorphic facial features and intellectual developmental disorder (CHDFIDD), is a very rare autosomal dominant genetic condition characterised by congenital heart defects, intellectual disability and characteristic facial features.

  8. Robertsonian translocation - Wikipedia

    en.wikipedia.org/wiki/Robertsonian_translocation

    Robertsonian translocations can only occur between chromosomes which have the centromere very close to one end. This means these chromosomes have a long arm which is particularly long, and a short arm which is particularly short. These are known as acrocentric chromosomes. Humans have five of these acrocentric chromosomes: 13, 14, 15, 21 and 22.

  9. Confined placental mosaicism - Wikipedia

    The next frequently involved are 9, 13, 15, 18, 20 and 22. [8] It has been observed that CPM involving the sex chromosomes usually has no adverse effects on fetal development. [9] The common autosomal trisomies (21, 18, 13) made up a smaller number of cases of mosaicism detected on CVS, but were more often confirmed in fetal tissue (19%). [3]
