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 ...
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.
In a small percentage of cases, trisomy 13 is caused by a rearrangement of chromosomal material between chromosome 13 and another chromosome. As a result, a person has the two usual copies of chromosome 13, plus extra material from chromosome 13 attached to another chromosome. These cases are called translocation trisomy 13.
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.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
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.
Partial monosomy of chromosome 13q is a monosomy that results from the loss of all or part of the long arm of chromosome 13 in human beings. It is a rare genetic disorder which results in severe congenital abnormalities which are frequently fatal at an early age.
Nearby regions on chromosome 16 may also be affected. Notably, deletion of SH2B1 is associated with obesity and may be involved in the pathogenesis of obesity observed in the syndrome. [9] 16p11.2 deletion typically occurs by de novo mutation. Approximately 7% of affected individuals inherit the mutation from a parent in an autosomal dominant ...
